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
