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.

discarded. Null interface helps to reduce system load.

preference-value: Preference of this route, in the range of 1 to 255.
reject:
Specifies the route as an unreachable route.
blackhole:
Specifies the route as a black hole route.
detect-group:
Specifies a detect group for the route.
detect-group-id: Detect group number, in the range of 1 to 25.
description text: Specifies a descriptive string
for the static route. The text argument is a string comprising 1 to 60
characters.
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
routes to the subnets directly connected to a router. If you do not specify the
preference when configuring a static route, the default value is 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.
