Trunk Settings

On the Trunk Settings page, you can specify Spanning Tree parameters for each trunk. For each port number listed in the Trunk column, the following fields
are available:
Priority — Indicates the priority assigned to the trunk for the Spanning Tree Protocol (0 to 255). A trunk with a higher priority is less likely to be blocked
l
if the Spanning Tree Protocol detects network loops. Low numeric value indicates a high priority.
Path Cost — Specifies the cost assigned to the trunk for the Spanning Tree Protocol (1 to 65535). A trunk with a lower cost is less likely to be blocked if
l
the Spanning Tree Protocol detects network loops.
NOTE: Use Fast Link if a device is connected to a trunk that requires network access immediately when the link comes up and cannot wait for a
Spanning Tree resolution.
Fast Link — Immediately enables the trunk in forwarding state when a link comes up. The trunk is not part of the Spanning Tree at that time, but will
l
participate in future Spanning Tree resolutions.
CLI Commands
The following table summarizes the equivalent CLI commands for items in the Spanning Tree/Trunk Settings page.

Console(config)#interface port-channel 1
Console(config-if)#bridge-group 1 path-cost 50
Console(config-if)#bridge-group 1 priority 0
Console(config-if)#bridge-group 1 portfast
VLAN
You can use virtual LANs (VLANs) to assign ports on the switch to any of up to 255 LAN groups. In conventional networks with routers, broadcast and multicast
traffic is split up into separate domains. Switches do not inherently support broadcast domains, which can lead to broadcast storms in large networks. By
using IEEE 802.1Q-compliant VLANs and GARP VLAN Registration Protocol (GVRP), you can organize any group of network nodes into separate broadcast
domains, confining broadcast and multicast traffic to the originating group. This also provides a more secure and cleaner network environment. For more
information on how to use VLANs, see "VLANs."
The VLAN page includes links to the following pages:
Configures the spanning tree path cost for the specified port
Configures the priority for the specified port
Sets a port to fast forwarding state
Usage
