C H A P T E R 1 0 IP Unicast Routing
• 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.
IP Multinetting Operation
To use IP multinetting, follow these steps:
1 Select a port on which IP multinetting is to run.
For example port 2.
2 Remove the port from the default VLAN, using the following
command:
config default delete port 2
3 Create a dummy protocol, by using the following command:
create protocol mnet
4 Create the multinetted subnets, by using the following com-
mands:
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 fol-
lowing command:
config net21 protocol ip
7 Assign the other subnets to the dummy protocol, by using the
following command:
config net22 protocol mnet
