Configuring a Default Gateway on a Catalyst 5000

Before IP management from another subnet or network can take place through Telnet, the sending device must know the routers that are connected to the local network to forward data for destinations outside the local network. Just as an end−user interface needs to have a defined default gateway, a switch needs to know the address of the interface of the route processor connected to the local subnet.

To define the gateway, in Global Configuration mode use the following command combined with the route processor or router IP address that is acting as the default gateway for the network:

Coriolis5000(config)# ip default−gateway 130.77.20.1

Verifying the IP Configuration on a Catalyst 5000

You can verify the IP configuration of the switch by using the show ip command:

Coriolis5000#show ip

IP Address: 130.77.20.15

Subnet Mask: 255.255.254.0

Default Gateway: 130.77.20.1

Management VLAN: 1

Domain name: coriolis.com

Name server 1: 130.77.17.190

Name server 2: 130.77.16.191

HM server : Enabled

HTTP port : 80

RIP : enabled

Enabling RIP on an RSM

To assign an IP routing protocol and network number, perform the following steps:

1.Assign a routing protocol (RIP) to the RSM. To do this, use the following commands in Global Configuration mode:

RSM1(config)#ip routing

RSM1(config)#router rip

2.Assign a network number to the route processor on the RSM by using the network command followed by the network number just as you would use with an external Cisco router’s interface:

RSM1(config−router)#network 172.16.0.0

3. Assign a VLAN to an IP address:

RSM1(config−router)#interface vlan 100

RSM1(config−if)#ip address 172.16.1.1 255.255.255.0

RSM1(config−if)#^Z
