IP Unicast Routing
2
Create and add ports to the sub-VLANs.
create vlan vsub1
con vsub1 add port 8-10
create vlan vsub2
config vsub2 add po 11-13
create vlan vsub3
config vsub3 add po 15-16
3
Configure the super-VLAN by adding the sub-VLANs.
config vsuper add subvlan vsub1
config vsuper add subvlan vsub2
config vsuper add subvlan vsub3
4
Optionally, disable communication among sub-VLANs.
disable subvlan-proxy-arp <super-VLAN name>
Verifying the VLAN Aggregation Configuration
The following commands can be used to verify proper VLAN
aggregation configuration.
•
show vlan
— Indicates the membership of sub-VLANs in a
super-VLAN.
•
show iparp
— Indicates an ARP entry that contains sub-VLAN
information. Communication with a client on a sub-VLAN must
occur before an entry is made in the ARP table.
Configuring DHCP/BOOTP Relay
Once IP unicast routing is configured, you can configure the switch
to forward Dynamic Host Configuration Protocol (DHCP) or
BOOTP requests coming from clients on subnets being serviced by
the switch and going to hosts on different subnets. This feature can
be used in various applications, including DHCP services between
Windows NT
*
servers and clients running Windows
*
95. To
configure the relay function, do the following:
1
Configure VLANs and IP unicast routing.
2
Enable the DHCP or BOOTP relay function, using the follow-
ing command:
enable bootprelay
