Spanning tree can be disabled for this topology. Because all VLANs are members of stg 1, by
default, the following turns off the group:
/c/l2/stg 1 /off
To set up the trunk between EXT1 and EXT2 to interface with each Cisco switch, use the
following (also, trunk failover is enabled with the syntax /c/l2/trunk 1/fail ena):
/c/l2/trunk 1
add ext1
add ext2
ena
fail ena
The Nortel GbESMs can be managed on VLAN 99:
/c/l3/if 99
ena
addr 10.99.0.243 /* addr 10.99.0.244
mask 255.255.255.0
vlan 99
For passing management traffic through the network, each Nortel GbESM should reference
the upstream Cisco switches as gateways on VLAN 99:
/c/l3/gw 1
ena
addr 10.99.0.245 /* addr 10.99.0.246
It is important here to enable the gateway with the /c/l3/gw 1/ena command or the entry
remains disabled.
Additionally, the sysName was set in order to easily identify the switch. All configuration
changes were applied and then saved to the flash:
/c/sys/ssnmp
name “GbESM_1” /* name “GbESM_2”
apply
save
