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. For routes that are temporarily unavailable for some
reasons (such as the policy configured or the interface is down), you can
hide them 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 read from 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
|
The route
is not lost when you perform the save operation and then restart the router.
Routes marked as Static are configured manually.
|
|
Unicast
|
The route
is an unicast route.
|
|
Age
|
Time period during which the route is
allowed in the routing table, in the form of hh:mm:ss.
|
|
Cost
|
Cost of the route

Note that:
To configure the management VLAN of a
switch operating as a cluster management device to be a cluster management VLAN
(using the management-vlan vlan-id command) successfully, make
sure the vlan-id argument provided in the management-vlan vlan-id
command is consistent with that of the management VLAN.

Description
Use the ip host command to configure

The interface-type can be NUll and Loopback. A null interface is
a virtual interface. Packets destined for a null interface is discarded. Null
interface helps to reduce system load.
next-hop: IP

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 value specified 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.

View

Parameter
None
Description
Use the shutdown command to shut
down a management VLAN interface.
Use the undo shutdown command to
bring up a management VLAN interface.
By default, a management VLAN interface is
down if all the Ethernet ports in the management VLAN are down, and the
management VLAN interface is up if one or more Ethernet ports in the management
VLAN are up.
If the Stack function
is enabled on the switch, the secondary devices of a stack will repeatedly
joint and leave the primary device after you use the shutdown command on
the management VLAN interface. This is normal and can be recovered after you
use the undo shutdown command on the management VLAN interface.
Example
# Bring up the management VLAN interface.
(Assume that VLAN 1 is the management VLAN.)
