Multinetting on a passport 1648T

[Routerman18250]

I have a customer who purchased a passport 1648T because the nortel sales rep told him he could multinet on his VLAN's with it and it could also do NAT.

I upgraded the switch to V1.1.1 code but the switch will not accept more than one IP per VLAN (port or Subnet) and I see no NAT capability.

Anyone have knowledge of this or know where there is documentation on Nortel's support site for this. Best I can find is multinetting on an 8600.

Hi,

The only way of 'multinetting' is to use IP subnet based vlans. I have implemented this at one customer where the baystack had one vlan with 3 subnets. Then configure the uplink port on the Passport for the 3 ip subnets. The packets will then drop into the subnets. BEWARE though, there is a known hardware limitation that means you HAVE to either tag or untag all ports associated with those vlans. you cannot mix tagged/untagged ports in an ip subnet based vlan on this product or you will lose ARP packets.

Thanks, I needed to put multiple subnets on each vlan. I spoke with Nortel TS and it can't be done on this switch.
