ratio: Maximum bandwidth ratio of broadcast traffic allowed in the specified VLAN. Its value ranges from 1 to 100 and defaults to 100. The smaller the ratio is, the less the broadcast traffic can pass through the VLAN.

pps pps: Specifies the maximum number of broadcast packets that can pass through a specific VLAN per second. Its value ranges from 1 to 148,800.

Description

Use the broadcast-suppression command to suppress broadcast traffic through a VLAN.

Use the undo broadcast-suppression command to reset the allowed broadcast traffic through a VLAN to the default value.

By default, the switch does not suppress broadcast traffic.

When the actual broadcast traffic exceeds the specified value, the system will discard the extra packets so that the bandwidth occupied by broadcast traffic can be kept within a specific ratio to ensure normal network operation.

The cards of S7500 series switches support different broadcast storm suppression modes, as listed in Table 1-1.

Table 1-1 Broadcast storm suppression modes and card types

Broadcast storm suppression mode	Type A card	Non-type-A card
VLAN pps suppression	Supported	Not supported
VLAN bandwidth ratio suppression	Supported	Not supported

& Note:

Type A cards include LS81FT48A, LS81FM24A, LS81FS24A, LS81GB8UA, LS81GT8UA, iSalience I, Salience I and Salience II.

A VLAN only supports one broadcast storm suppression mode at one time. If you configure broadcast storm suppression modes multiple times for a VLAN, the latest configuration will overwrite the previous configuration.

# Allow broadcast traffic to occupy 20% bandwidth in VLAN 2.

1.1.7 shutdown

Syntax

shutdown

undo shutdown

View

VLAN interface view

Parameters

None

Description

Use the shutdown command to disable a VLAN interface.

Use the undo shutdown command to enable a VLAN interface.

By default, a VLAN interface is enabled. In this scenario, the VLAN interface’s status is determined by the status of its ports, that is, if all the ports of the VLAN are down, the VLAN interface is down (disabled); if one or more ports of the VLAN are up, the VLAN interface is up (enabled).

If a VLAN interface is disabled, its status is not determined by the status of its ports.

You can use the undo shutdown command to enable a VLAN interface when its related parameters and protocols are configured. When a VLAN interface fails, you can use the shutdown command to disable the interface, and then use the undo shutdown command to enable this interface again, which may restore the interface.

The operation of enabling/disabling a VLAN interface does not influence any Ethernet port belonging to this VLAN.

Examples

# Disable VLAN-interface 2 and then enable it.

View

Parameters

access: Sets the port as an access port.

hybrid: Sets the port as a hybrid port.

trunk: Sets the port as a trunk port.

Description

Use the port link-type command to set the link type of the current Ethernet port.

Use the undo port link-type command to restore the default link type.

The three types of ports can co-exist on the same Ethernet switch. However, a trunk port cannot be directly switched to a hybrid port, and vice versa. To set a trunk/hybrid port to another type (different from access), you must first set the port to an access port and then set the access port to the required type. For example, a trunk port cannot be directly set to a hybrid port. You must set the trunk port to an access port and then set it to a hybrid port.

By default, the link type of any port is access.

undo protocol-vlan { protocol-index [ to protocol-end ] | all }

View

VLAN view

Parameters

at: Specifies an AppleTalk (AT)-based VLAN.

ip [ ip-address [ net-mask ] ]: Specifies an IP-based VLAN. The ip-address argument specifies IP address and the net-mask argument specifies subnet mask. The default subnet mask is the mask of the network where ip-address belongs.

ipx { ethernetii | llc | raw I snap }: Specifies IPX protocol-based VLAN. The ethernetii, llc, raw and snap keywords indicate four encapsulation types.

mode: Specifies VLAN based on other protocol type and encapsulation format.

ethernetii [ etype etype-id ]: Specifies EthernetII encapsulation-based VLAN. The etype-id argument indicates the Ethernet type of the incoming packets, and its value ranges from 600 to FFFF.

llc [ dsap dsap-id [ ssap ssap-id ] | ssap ssap-id ]: Specifies VLAN based on logical link control encapsulation format. The dsap-id argument indicates the destination service access point and its value ranges from 0 to FF. The ssap-id argument indicates the source service access point and its value ranges from 0 to FF.

snap [ etype etype-id ]: Specifies VLAN based on sub-network access protocol (SNAP) encapsulation format. The etype-id argument indicates the Ethernet type of incoming packets and its value ranges from 600 to FFFF.

protocol-index: Beginning protocol index, ranging from 0 to 6. Its value must be smaller than or equal to the value of the protocol-end argument. If this argument is not specified, the system will assign an index automatically.

protocol-end: End protocol index, ranging from 0 to 6. Its value must be greater than or equal to the value of the protocol-index argument.

all: Specifies all protocol indexes.

Description

Use the protocol-vlan command to configure the protocol template used for classifying protocol-based VLANs.

Use the undo protocol-vlan command to cancel the configuration.

Caution:

In a VLAN, it is not allowed to configure two templates with the same protocol type and encapsulation format. The encapsulation defined by a user-defined template is the same as that defined by a standard template if the parameters of the user-defined template adopt some special values. In this scenario, the user-defined template and the standard template cannot be configured in the same VLAN.

Pay attention to the following notices about the template configuration:

l It is not allowed to configure both ipx llc standard template and LLC user-defined template in the same VLAN.

l It is not allowed to configure both ipx raw standard template and LLC user-defined template whose dsap and ssap are both ff in the same VLAN.

l It is not allowed to configure both ipx ethernetii standard template and EthernetII user-defined template whose etype is 8137 in the same VLAN.

l It is not allowed to configure both ipx snap standard template and SNAP user-defined template whose etype is 8137 in the same VLAN.

l When the values of the dsap-id and ssap-id arguments are AA, the packet encapsulation type is not llc but snap. To avoid template conflict, the system disables the value AA for the dsap-id and ssap-id arguments when you configure LLC user-defined template.

In addition, pay attention to the following notices about IP template:

l If a packet can match both IPv4-based VLAN and the VLAN based on other protocol, IPv4-based VLAN takes higher priority.

l ip [ ip-address [ net-mask ] ] defines IPv4-based VLAN. If you want to define the VLANs based on IP or other encapsulation formats, use mode { ethernetii [ etype etype-id ] } and snap [ etype etype-id ], in which, etype-id is 0x0800.
