IP address and routing management
B
Viewing inband management IP addresses and routes
The portShow inbandmgmt command displays the addresses that are currently configured for that
GE port number and a status of Inband Management (Enabled/Disabled). To display the routing
table, use the existing portShow iproute command. There is a status flag for the IP routes to signify
if a route is used for the management interfaces. After the route definition is printed, a
Management option appears at the end of the line. This indicates that the route is using one of the
internal interfaces.
The portCfgShow inbandmgmt command displays the addresses that are currently configured for
that GE port number. The portCfgShow command also displays any Inband Management routes
configured in the Iproute Configuration section.
To provide connection between the CP and the management station, IP routes must be added to all
Ethernet devices between the two. To make sure that only traffic destined for the management
interface on the CP is sent to the 7500s, it is recommended you use host-specific routes for the
7500 management destination routes. This ensures that the 7500 switch is not acting as a full IP
router between the various subnets. To ensure proper connectivity, routes must be added to each
hop along the desired path.
Viewing inband management IP routes
1. Connect to the switch and log in as admin.
2. Enter the portShow iproute command specifying the GE port you want to view.
The portShow command has additional information displayed in the iproute display option. The
routes display the Management designation if they are routes associated with the CP to GE
connectivity as shown below:
switch:admin> portshow iproute ge1
Port: ge1

IPv6 Address Len Gateway Metric
---------------------------------------------------------------------------------
In this example, the interface on the GE port processor is set up with an address of
192.168.255.2/24 and the address on inbd0 on the CP is set up with the address
192.168.255.1/24. So there is an ‘Interface Management’ route on the GE port processor for
192.168.255.0/24 with a gateway 192.168.255.2 and an ‘Interface Management’ route on the CP
for 192.168.255.0/24 with gateway 192.168.255.1. Likewise there is a ‘Management’ route on
the GE port processor for 10.1.1.61/32 with gateway 192.168.255.1, and a ‘Management’ route
on the CP for 192.168.112.60/32 with gateway 192.168.255.2. In this example, the CP
management address is 10.1.1.61, and the management station is at address 192.168.112.60. If
an additional route is needed on the GE port processor to communicate with the management
station, this will not be labeled as a ‘Management’ route as it does not use the internal devices as
it’s gateway.
