OUTING
• The FDB aging timer is automatically set to 3,000 seconds (50 minutes).
• If you are using a UDP or DHCP relay function, only the "primary" VLAN that is
configured with the IP protocol filter is capable of servicing these requests.
• The VLAN default should not be used for multinetting.

PERATION
To use IP multinetting, follow these steps:
1 Select a slot (BlackDiamond switch only) and port on which IP multinetting is to
run.
For example, slot 1, port 2 on a BlackDiamond switch, or port 2 on a Summit switch.
2 Remove the port from the default VLAN, using the following command:
config default delete port 1:2
(BlackDiamond switch)
or
config default delete port 2
(Summit switch)
3 Create a dummy protocol, by using the following command:
create protocol mnet
4 Create the multinetted subnets, by using the following commands:
create vlan net21
create vlan net22
5 Assign IP addresses to the net VLANs, by using the following commands:
config net21 ipaddress 123.45.21.1 255.255.255.0
config net22 ipaddress 192.24.22.1 255.255.255.0
6 Assign one of the subnets to the IP protocol, by using the following command:
config net21 protocol ip
7 Assign the other subnets to the dummy protocol, by using the following command:
config net22 protocol mnet
8 Assign the subnets to a physical port, by using the following commands:
config net21 add port 1:2
config net22 add port 1:2
9 Enable IP forwarding on the subnets, by using the following command:
enable ipforwarding
