Configuring IP

IP Configuration

IP is enabled on the switch by default and there are few options that can, or need to be, configured. This
section provides instructions for some basic IP configuration options.

Configuring the Router Primary Address

The router primary address is used by advanced routing protocols (e.g., OSPF) to identify the switch on
the network. It is also the address that is used to access the switch for management purposes.
Use the ip router primary-address
command, followed by the IP address. For example, to configure a router primary address of
172.22.2.115, you would enter:
-> ip router primary-address 172.22.2.115

Configuring the Router ID

By default, the primary address of the router is used as the router ID. However, if a primary address has
not been configured, the router ID is used by OSPF to identify the switch on the network. The router ID
can be any 32-bit number.
Use the ip router router-id
address. For example, to configure a router ID of 172.22.2.115, you would enter:
-> ip router router-id 172.22.2.115

Configuring the Time-to-Live (TTL) Value

The TTL value is the default value inserted into the TTL field of the IP header of datagrams originating
from the switch whenever a TTL value is not supplied by the transport layer protocol. The value is
measured in hops.
Use the ip default-ttl
example, to set a TTL value of 75, you would enter:
-> ip default-ttl 75
The default hop count is 64. The valid range is 1 to 255. Use the
default TTL value.
