How to Configure Gigabit EtherSwitch EHWICs

Configuring the Cisco Gigabit EtherSwitch EHWIC

OL-23155-01

Note We recommend that you avoid configuring the hello time, forward delay time, and maximum age time

manually after configuring the switch as the root bridge.

To configure the switch as the root, use the spanning-tree vlan vlan_ID root primary [diameter

net-diameter [hello-time seconds]] command in global configuration mode. Use the no form of this

command to restore the defaults.

Disabling Spanning Tree

To disable spanning tree on a per-VLAN basis, use the no spanning-tree vlan vlan_ID command in

global configuration mode.

Verifying that Spanning Tree is Disabled

Use the show spanning-tree vlan command to verify that the spanning tree is disabled, as shown in the

example below:

Router#show spanning-tree vlan 200

Spanning tree instance for VLAN 200 does not exist.

Configuring MAC Table Manipulation

Port security is implemented by providing the user with the option to make a port secure by allowing only

well-known MAC addresses to send in data traffic. Up to 200 secure MAC addresses per platform are

supported.
