Vlan & Cos - Dell PowerConnect 3048 User Manual

Cost — Assigned to this port for the Spanning Tree Protocol (1- 65536). A port with a lower cost is less likely to be blocked if the Spanning Tree Protocol
l
is detecting network loops.
Fast Link — Immediately enables the port in forwarding state when a link comes up. The port is not part of the Spanning Tree at that time, but will
l
participate in future Spanning Tree resolutions.
NOTE: This option is useful if a device is connected to a port that requires network access immediately when the link comes up and cannot wait for a
Spanning Tree resolution.

¡
CoS information.
<T>: Port is a member of the VLAN. All packets transmitted by the port will be tagged, that is, carry a tag and therefore carry VLAN or CoS
¡
information.
<BLANK>: Port is not a member of the VLAN. Packets associated with this VLAN will not be transmitted by the port.
