802.1w Rapid Spanning Tree Protocol (RSTP) and 802.1d Spanning Tree Protocol (STP)
802.1p Spanning-Tree Protocol (STP)
In figure 13-19:
•
Port A1 and Trk1 (trunk 1; formed from ports 2 and 3) are redundant
fast-uplink STP links, with trunk 1 forwarding (the active link) and
port A1 blocking (the backup link). (To view the configuration for port
A1 and Trk1, see figure 13-17 on page 13-35.)
•
If the link provided by trunk 1 fails (on both ports), then port A1 begins
forwarding in fast-uplink STP mode.
•
Ports A5, A6, and A24 are connected to end nodes and do not form
redundant links.
CLI: Viewing and Configuring Fast-Uplink STP
Using the CLI to View Fast-Uplink STP.
You can view fast-uplink STP
using the same
show
commands that you would use for standard STP opera-
tion:
Syntax:
show spanning-tree
Lists STP status.
show spanning-tree config
Lists STP configuration for the switch
and for individual ports.
For example, figures 13-20 and 13-21 illustrate a possible topology, STP status
listing, and STP configuration for a Series 4100GL switch with:
■
STP enabled and the switch operating as an Edge switch
■
Port A1 and trunk 1 (Trk1) configured for fast-uplink STP operation
■
Several other ports connected to PC or workstation end nodes
