Table 1-5 Description on the fields of the display ip routing-table acl command

Field	Description
Destination	Destination address
Mask	Mask
Protocol	Routing protocol that discovers the route
Preference	Route preference
NextHop	Next hop IP address
Interface	Outbound interface, through which packets destined for the destination network segment are to be transmitted
State	Descriptions on the route state are as follows:
	ActiveU	Valid unicast route. “U” stands for unicast.
	Blackhole	Blackhole route is the same as reject route except that a router drops a packet traveling along a blackhole route without sending ICMP unreachable messages to the source of the packets.
	Delete	The route is deleted.
	Gateway	The route is not a direct route.
	Hidden	The route is a hidden route. The system hides routes that are temporarily unavailable for some reasons (such as the policy configured or the interface is down) for later use.
	Holddown	The route is held down. Holddown is a kind of route advertisement policy used in some D-V (distance vector) routing protocols (such as RIP) to avoid the propagation of some incorrect routes and improve the transmission speed of route-unreachable information. For details, refer to corresponding routing protocols.
	Int	The route is discovered by the internal gateway protocol (IGP).
	NoAdvise	The route is not advertised when the router advertises routes based on policies
	NotInstall	The route are not loaded to the core routing table but can be advertised. Normally, the routes with the highest preference in the routing table are loaded to the core routing table and are advertised.
	Reject	The packets travel along the route will be dropped. Besides, the router sends ICMP unreachable messages to the source of the dropped packets. The Reject routes are usually used for network testing.
	Retain	The route is not deleted when the routes in the core routing table are deleted. You can enable static routes to remain in the core routing table by configure them to be in retain state.
	Static	Static routes configured manually on the router are marked as static. Such routes are not lost when you perform the save operation and then restart the router.
	Unicast	The route is a unicast route.
Age	Time period during which the route is allowed to be in the routing table, in the form of hh:mm:ss.
Cost	Cost of the route

interface Vlan-interface

Syntax

interface Vlan-interface vlan-id

undo interface Vlan-interface vlan-id

View

System view

Parameter

vlan-id: ID of the management VLAN, in the range of 1 to 4094.

Description

Use the interface Vlan-interface command to create a management VLAN interface and enter management VLAN interface view.

Use the undo interface Vlan-interface command to remove the management VLAN interface.

Before creating a management VLAN interface, make sure the VLAN identified by the vlan-id argument is created and is configured as the management VLAN.

Note that:

To create the VLAN interface for the management VLAN on a switch operating as the management device in a cluster, make sure the ID of the management VLAN is consistent with that of the cluster management VLAN, that is, the vlan-id argument in the management-vlan vlan-id command when you configure the cluster management VLAN. Otherwise, the configuration fails.

Example

# Create VLAN 10 and configure it as the management VLAN. Create VLAN 10 interface and enter VLAN 10 interface view.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

Parameter

ip-address: IP address to be assigned to the management VLAN interface.

mask: Mask of the IP address to be assigned to the management VLAN interface. The mask can be in dotted decimal notation or an integer in the range of 0 to 32.

Description

Use the ip address command to assign an IP address with the mask to a management VLAN interface.

Use the undo ip address command to remove the IP address assigned to a management VLAN interface.

Related command: display interface Vlan-interface.

Example

# Assign the IP address 192.168.0.51 (with the mask 255.255.255.0) to the management VLAN interface. (Assume that VLAN 1 is the management VLAN.)

ip route-static

Syntax

ip route-static ip-address { mask | mask-length } { interface-type interface-number | next-hop } [ preference preference-value ] [ reject | blackhole ] [ description text ]

undo ip route-static ip-address { mask | mask-length } [ interface-type interface-number | next-hop ] [ preference preference-value ]

View

System view

Parameter

ip-address: Destination IP address, in dotted decimal notation.

mask: IP address mask, in dotted decimal notation.

mask-length: Mask length, in the range of 0 to 32.

interface-type interface-number: Next hop outgoing interface. Currently, you can specify a NULL interface only. A null interface is a virtual interface. Packets destined for a null interface are discarded, helping to reduce system load.

next-hop: IP address of the next hop of this route, in dotted decimal notation.

preference-value: Preference of this route, in the range of 1 to 255.

reject: Specifies the route as an unreachable route. When a static route destined for a destination address is of the reject attribute, all the IP packets destined for the destination address are discarded, and the source host is informed that the destination address is unreachable.

blackhole: Specifies the route as a black hole route. When a static route destined for a destination address is of the blackhole attribute, the outgoing interface of the route is Null 0 regardless of the next hop address. All the IP packets destined for the destination address are discarded, and the source host is not informed that the destination address is unreachable.

description text: Specifies a descriptive string for the static route. The text argument is a case-sensitive string of 1 to 60 characters (including the space).

Description

Use the ip route-static command to configure a static route.

Use the undo ip route-static command to remove a static route.

By default, the system can obtain the subnet route directly connected to the router. When you configure a static route, if no preference is specified for the route, the preference defaults to 60. Note that routes with the same destinations, the same next hops, but different preferences are different routes. Among these routes, the one with least preference (which means the highest preference) is chosen to be the current route. A route configured using the ip route-static command is a reachable route if neither of the reject and blackhole keywords is specified.

Note the following when configuring a static route:

l          The next hop address of a static route cannot be the VLAN interface address of the local switch.

l          A static route with both its destination IP address and mask both being 0.0.0.0 is the default route. When no matched entry is found in the routing table, a received packet is forwarded according to the default route.

Related command: display ip routing-table.

Example

# Configure the next hop of the default route as 129.102.0.2.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

Example

# Configure VLAN 2 as the management VLAN.
