Define the Maximum Age
If a bridge does not hear BPDUs from the root bridge within a specified interval, it
assumes that the network has changed and recomputes the spanning-tree topology.
To change the default interval setting, enter the following command in Configure mode:
Configuring a Port or Protocol based VLAN
To create a port or protocol based VLAN, perform the following steps in the Configure

To create a VLAN, perform the following command in the Configure mode.
Adding Ports to a VLAN
To add ports to a VLAN, perform the following command in the Configure mode.
Configuring VLAN Trunk Ports
The SSR supports standards-based VLAN trunking between multiple SSRs as defined by
IEEE 802.1Q. 802.1Q adds a header to a standard Ethernet frame which includes a unique
VLAN id per trunk between two SSRs. These VLAN ids extend the VLAN broadcast
domain to more than one SSR.
To configure a VLAN trunk, perform the following command in the Configure mode.
Change the amount of time a bridge will
wait to hear BPDUs from the root bridge. stp set bridging max-age <num>
Create a VLAN. vlan create <vlan-name> <type> id <num>
Add ports to a VLAN. vlan add ports <port-list> to <vlan-name>
Configure 802.1Q VLAN trunks. vlan make <port-type> <port-list>
