TRILL commands

TRILL requires a license to run on the device. For information about feature licensing, see Fundamentals Configuration Guide.

auto-cost enable

Use auto-cost enable to enable automatic link cost calculation for TRILL ports.

Use undo auto-cost enable to disable automatic link cost calculation for TRILL ports.

Syntax

auto-cost enable

undo auto-cost enable

Default

Automatic link cost calculation is enabled for TRILL ports.

Views

Predefined user roles

network-admin

mdc-admin

Usage guidelines

The link cost of a TRILL port can be automatically calculated by the system or manually set.

·     A manually set link cost takes precedence over a calculated link cost.

·     If no link cost is set and automatic link cost calculation is enabled, the calculated link cost takes effect.

·     If no link cost is set and automatic link cost calculation is disabled, the default link cost of 2000 is used.

The system automatically calculates the link cost of a TRILL port by using the following formula: link cost = 20000000000000/interface baud rate.

Examples

# Disable automatic link cost calculation for TRILL ports.

<Sysname> system-view

[Sysname] trill

[Sysname-trill] undo auto-cost enable

Parameters

tree-root nickname: Specifies a TRILL distribution tree by its root RB's nickname, a hexadecimal number in the range of 0x0 to 0xFFFF.

Usage guidelines

The RB uses the TRILL RPF check table to check whether the incoming port of a multidestination frame is valid. The egress RB for a multidestination frame is the root bridge of the frame's distribution tree. The RB checks the RPF check table for the frame's expected incoming port based on the frame's egress and ingress RB nicknames. If the frame is not received on the expected incoming port, the RB considers the frame invalid and drops it.

Examples

# Display TRILL RPF check table entries for the TRILL distribution tree that is rooted at the RB 0x899B.

mdc-admin

Parameters

flood-count flooding-count: Specifies the maximum number of LSPs that can be fast advertised. The value range for the flooding-count argument is 1 to 15, and the default value is 5.

max-timer-interval flooding-interval: Specifies the delay before fast advertisement is performed. The value range for the flooding-interval argument is 0 to 50000 milliseconds. The default value is 0, which indicates that LSP fast advertisement is performed without delay.

Usage guidelines

This command is available in Release 1138P01 and later versions.

LSP fast advertisement enables TRILL to immediately advertise the specified number of LSPs that invoke SPF calculation. This mechanism improves network convergence time.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Enable TRILL LSP fast advertisement, set the maximum number to 10 for fast advertised LSPs, and set the advertisement delay to 10 milliseconds.

Views

Predefined user roles

network-admin

mdc-admin

Usage guidelines

This command is available in Release 1138P01 and later versions.

TRILL multicast routing entries are classified into three levels according to the following key combinations:

·     RB—Root bridge of a TRILL distribution tree.

·     RB+VLAN—Root bridge and VLAN of a TRILL distribution tree.

·     RB+VLAN+MAC—Root bridge and VLAN of a TRILL distribution tree and a MAC address.

An entry that is identified by fewer keys is at a higher level.

The incremental flush feature enables the device to compare the outgoing port list and local receiving flag of an entry with its next higher level entry. If the two entries have the same outgoing port list and local receiving flag, the higher level entry is issued to the TRILL FIB. For example, if entry RB 2 and entry RB 2+VLAN 10 have the same outgoing port list and local receiving flag, entry RB 2 is issued.

This feature reduces the number of flushed entries in the scenarios where an entry and its next higher level entry have the same outgoing port list and local receiving flag. Enabling this feature in other scenarios causes the system to issue a large number of entries at the same time and degrades performance.

Usage guidelines

This command is available in Release 1138P01 and later versions.

Setting the SA bit prevents neighbors from advertising the adjacency with the GR restarter when the forwarding table is not usable on the restarter. This prevents route blackholes by temporarily excluding the restarter from the SPF calculation on other RBs. If fast restart is required, you can suppress the SA bit.

Examples

# Suppress the SA bit during graceful restart.

Parameters

delay: Specifies the delay timer in the range of 1 to 3600 seconds.

Usage guidelines

This command is available in Release 1138P01 and later versions.

When a distribution tree is added, the RB switches ingress traffic of some VLANs that use the RB as the AVF to the new tree to implement load balancing. However, the RB cannot use the new distribution tree to forward traffic before other RBs are ready to use the new tree. In this case, you can set a delay timer for the RB to switch ingress traffic to the new distribution tree.

Examples

# Set the delay timer to 600 seconds for the RB to switch ingress traffic to a new distribution tree.

<Sysname> system-view

[Sysname] trill

[Sysname-trill] ingress assign-delay 600

Views

TRILL view

Predefined user roles

network-admin

mdc-admin

Parameters

p2p-ignore: Uses one of the equal-cost routes between the DRB and its neighbor to forward multicast traffic when the pseudonode bypass feature is enabled on the DRB. If you do not specify this keyword, all the equal-cost routes are used to share traffic. To communicate with a third-party device, you can specify this keyword as required. This keyword is available in Release 1138P01 and later versions.

Usage guidelines

When multicast ECMP is disabled, TRILL distribution trees do not use equal-cost routes to share traffic. When multicast ECMP is enabled, TRILL assigns equal-cost routes to multiple TRILL distribution trees to improve load sharing performance.

For multicast traffic to be forwarded correctly, make sure the status of TRILL multicast ECMP is the same across the TRILL network.

Parameters

nickname: Specifies an RB by its nickname, a hexadecimal number in the range of 0x1 to 0xFFBF.

priority priority: Specifies a priority for the RB to hold the nickname. The value range for the priority argument is 129 to 255, and the default value is 192.

Usage guidelines

A nickname is an RB's address in the TRILL network.

In the TRILL network, when multiple RBs hold the same nickname, the RB with the highest priority uses the nickname.

When the RBs also have the same priority, the RB with the highest system ID uses the nickname. The system automatically assigns new nicknames to the other RBs.

Examples

# Set the nickname to 0x0001 for the RB, and set the priority to 198 for the RB to hold the nickname.

Parameters

-c count: Specifies the number of OAM echo requests that are sent to the destination. The value range is 1 to 4294967295, and the default value is 5.

-h ttl: Specifies the TTL value of OAM echo requests. The value range is 1 to 63, and the default value is 63.

-i interface-type interface-number: Specifies the source interface for OAM echo requests. If you do not specify this option when multiple equal-cost routes to the destination exist, the system uses the first egress interface as the source interface.

-m interval: Specifies the sending interval for OAM echo requests. The value range is 1 to 10000 milliseconds, and the default value is 200 milliseconds.

-priority priority: Specifies the 802.1p priority in the inner Ethernet header of the OAM echo requests. The value range is 0 to 7, and the default value is 0. A higher value indicates a higher priority.

-t timeout: Specifies the timeout time of an OAM echo reply. The value range is 0 to 65535 milliseconds, and the default value is 2000 milliseconds. If the source does not receive an OAM echo reply within the timeout, it considers the OAM echo reply times out.

nickname: Specifies a destination RB by its nickname for Layer 2 forwarding, in the range of 0x1 to 0xFFBF in hexadecimal format. To view the Layer 2 forwarding nickname of an RB, use the display trill brief command.

Parameters

maximum-interval: Specifies the maximum LSP generation interval in the range of 1 to 120 seconds.

minimum-interval: Specifies the minimum LSP generation interval in the range of 10 to 60000 milliseconds. The value must be a multiple of 10 and smaller than the maximum LSP generation interval.

Predefined user roles

network-admin

mdc-admin

Parameters

time: Specifies the LSP maximum age in the range of 3 to 65535 seconds.

Usage guidelines

The RB uses the configured LSP maximum age as the remaining lifetime of the LSPs that it originates. When the RB detects that the remaining lifetime of an LSP reaches 0 seconds in the LSDB, the RB performs the following tasks:

1.     Removes the LSP's content.

2.     Keeps the LSP's digest.

3.     Sets the LSP's remaining lifetime to 0 and purges the LSP from the network by advertising the LSP to other RBs.

The actual refresh interval of an LSP is affected by both the minimum LSP interval and the maximum number of LSPs transmitted per interval. To prevent LSPs from being aged out accidentally, set the LSP maximum age and the LSP refresh interval appropriately.

Examples

# Set the LSP maximum age to 1500 seconds.

Parameters

time: Specifies the LSP refresh interval in the range of 1 to 65534 seconds.

Usage guidelines

A locally originated LSP is forcibly refreshed when its remaining life time is no greater than n: n = LSP maximum age – LSP refresh interval. This mechanism avoids frequent LSP aging and ensures network stability.

The actual refresh interval of an LSP is affected by both the minimum LSP interval and the maximum number of LSPs transmitted per interval. To prevent LSPs from being aged out accidentally, set the LSP maximum age and the LSP refresh interval appropriately.

Parameters

maximum-interval: Specifies the maximum SPF calculation interval in the range of 1 to 120 seconds.

minimum-interval: Specifies the minimum SPF calculation interval in the range of 10 to 60000 milliseconds. The value must be a multiple of 10 and smaller than the maximum SPF calculation interval.

incremental-interval: Specifies the SPF calculation incremental interval in the range of 10 to 60000 milliseconds. The value must be a multiple of 10 and smaller than the maximum SPF calculation interval.

Usage guidelines

The RB uses the SPF algorithm to calculate a shortest path tree with itself as the root based on the local LSDB. The RB determines the next hop according to the shortest path tree.

By adjusting the SPF calculation timer parameters, you can prevent frequent network changes from consuming excessive bandwidth and device resources.

When the network is stable, the SPF calculation interval for continuous calculations is reduced to the minimum interval. When the network is unstable, the SPF calculation interval is added by incremental-interval × 2n-2 (n is the number of continuous SPF calculation times) for each SPF calculation until the maximum interval is reached.

Examples

# Set the maximum SPF calculation interval to 15 seconds, the minimum interval to 100 milliseconds, and the incremental interval to 200 milliseconds.

Parameters

-f first-ttl: Specifies the TTL value of the first packet sent to the destination. The value range is 0 to 63, and the default value is 0. This TTL cannot be greater than the value of the max-ttl argument.

-i interface-type interface-number: Specifies the source interface for OAM echo requests. If you do not specify this option when multiple equal-cost routes to the destination exist, the system uses the first egress interface as the source interface.

-m max-ttl: Specifies the maximum TTL allowed for an echo request. The value range is 0 to 63, and the default value is 63. This TTL cannot be smaller than the value of the first-ttl argument.

-priority priority: Specifies the 802.1p priority in the inner Ethernet header of the OAM echo request. The value range is 0 to 7, and the default value is 0. A higher value indicates a higher priority.

-q packet-number: Specifies the number of requests to send per hop. The value range is 1 to 10, and the default value is 3.

-t timeout: Specifies the timeout time of an OAM echo reply. The value range is 0 to 65535 milliseconds, and the default value is 2000 milliseconds. If the source does not receive an OAM echo reply within the timeout, it considers the OAM echo reply times out.

-v: Displays detailed information about the path that the TRILL packets traverse from the source RB to the destination RB. If you do not specify this keyword, the command displays brief information about the path.

-name: Displays the physical port name in the ReceivingPort and OutputPort fields when you display detailed information about the path that the TRILL OAM packets traverse from the RB to a destination RB. If you do not specify this keyword, both the ReceivingPort and OutputPort fields display only the circuit ID of a physical port.

nickname: Specifies a destination RB by its nickname for Layer 2 forwarding, in the range of 0x1 to 0xFFBF in hexadecimal format. To view the Layer 2 forwarding nickname of an RB, use the display trill brief command.

Usage guidelines

This command is available in Release 1138P01 and later versions.

After identifying network failure by using the ping trill command, use the tracert trill command to locate failed nodes.

The output from the tracert trill command includes the nicknames of all RBs that the packets traverse from source to destination. Asterisks (* * *) are displayed if no reply is received within the timeout period or a TRILL-enabled RB does not support the tracert trill command. The RB that does not support the tracert trill command cannot reply with a hop count error notification but can forward packets for tracert TRILL operation.

To abort the tracert TRILL operation during the execution of the command, press Ctrl+C.

Parameters

priority: Specifies a priority value in the range of 0 to 127. A higher priority value indicates a higher priority.

Usage guidelines

On a broadcast network, TRILL must elect a DRB. An RB with a higher DRB priority is preferred in DRB election. When two RBs have the same DRB priority, the RB with a higher MAC address takes precedence.

Usage guidelines

Before you enable TRILL on a port, first enable TRILL globally.

Enable or disable TRILL on all ports in a VLAN, so that the ports in a VLAN have the same TRILL status (enabled or disabled).

To avoid loops, use the following procedure to enable TRILL on a port:

1.     Shut down the port by using the shutdown command.

2.     Enable TRILL and assign the port to VLANs.

3.     Bring up the port by using the undo shutdown command.

Do not enable the spanning tree protocol on a TRILL port. Because the spanning tree protocol is enabled by default on all ports, the spanning tree feature takes effect on all ports when you enable the spanning tree feature globally. After the spanning tree protocol is enabled globally, you must disable the spanning tree feature on TRILL ports. For more information about the spanning tree feature, see Layer 2—LAN Switching Configuration Guide.

Parameters

access [ alone ] : Configures the link type as access. When the alone keyword is not specified, the port is configured as an access port without the alone attribute. The port can process only local data frames and Hello frames. When the alone keyword is specified, the port is configured as an access port with the alone attribute. The port does not send or receive Hello frames and does not participate in DRB election or AVF negotiation.

hybrid: Configures the link type as hybrid. A hybrid port combines the attributes of an access port and a trunk port. It can process local data frames and passing data frames.

trunk: Configures the link type as trunk. A trunk port can process passing data frames and some Layer 2 protocol packets (for example, LLDP packets). It cannot process local data frames.

network-admin

mdc-admin

Parameters

time: Specifies the AVF inhibition time in the range of 0 to 30 seconds.

Usage guidelines

The AVF of a VLAN guarantees that frames of the VLAN enter and leave a broadcast network through the same port. Other RBs on the broadcast network do not process frames from the VLAN.

To avoid loops, the RB that acts as the AVF suppresses its AVF role during the inhibition time when one of the following conditions exists:

·     The RB detects a root bridge change on the broadcast network.

·     Other RBs advertise a different AVF for the VLAN.

When the inhibition time expires, the RB restores its AVF role if it is still the AVF of the VLAN. Configuration in Layer 2 Ethernet interface view takes effect only on the current port. Configuration in Layer 2 aggregate interface view takes effect on the current interface and its member ports. Configuration on the member port of an aggregate interface takes effect after the member port leaves the aggregation group.

Parameters

interval: Specifies an interval in the range of 1 to 600 seconds.

Usage guidelines

On a broadcast network, the RB advertises CSNPs at the CSNP interval to perform network-wide LSDB synchronization if it is elected as the DRB. A CSNP records all LSP digests of the RB's local LSDB. A remote RB compares a received CSNP against its local LSDB to examine whether some LSPs age out or are missing. If the CSNP has an LSP digest that the local LSDB does not have, the remote RB sends a PSNP packet to request the LSP information.

Parameters

interval: Specifies the Hello interval. The value range is 3 to 255 seconds in Release 1135. The value range is 1 to 255 seconds in Release 1138P01 and later versions.

Usage guidelines

The RB advertises Hello frames at the Hello interval to maintain a TRILL adjacency. The shorter the Hello interval, the faster the network convergence. However, a shorter Hello interval consumes more system resources.

This command sets the Hello interval for an RB. The Hello interval of a DRB is 1/3 of the Hello interval of an RB. This allows for DRB failures to be quickly detected.

The adjacency holding time is obtained by multiplying the Hello interval by the Hello multiplier. The RB advertises the adjacency holding time to neighbors through Hello frames. If a neighbor does not receive any Hello frames from the RB within the adjacency holding time, it removes the TRILL adjacency with the RB.

The adjacency holding time cannot exceed 65535 seconds.

count: Specifies the maximum number of LSPs transmitted per interval, in the range of 1 to 1000.

Usage guidelines

To avoid frequent LSP aging in the network, RBs periodically advertise LSPs. The actual refresh interval of an LSP is affected by both the minimum LSP interval and the maximum number of LSPs transmitted per interval. To prevent LSPs from being aged out accidentally, set the LSP maximum age and the LSP refresh interval appropriately.
