Practical Exercise 8-2 Solution 221

Example 8-47 shows that Bridge group 1 is running the IEEE Spanning Tree Protocol.

Example 8-48 shows the IP and MAC addresses of lab-827A and lab-827B. show arp is a

useful command to verify whether bridging is conﬁgured properly.

Example 8-47 Displaying the Spanning Tree Protocol (IEEE)

lab-6400NRP#show spanning-tree 1

Bridge group 1 is executing the ieee compatible Spanning Tree protocol

Bridge Identifier has priority 32768, address 0000.0c7f.70fc

Configured hello time 2, max age 20, forward delay 15

We are the root of the spanning tree

Topology change flag not set, detected flag not set

Number of topology changes 4 last change occurred 00:35:16 ago

from ATM0/0/0.235

Times: hold 1, topology change 35, notification 2

hello 2, max age 20, forward delay 15

Timers: hello 0, topology change 0, notification 0, aging 300

Port 6 (ATM0/0/0.135) of Bridge group 1 is forwarding

Port path cost 14, Port priority 128, Port Identifier 128.6.

Designated root has priority 32768, address 0000.0c7f.70fc

Designated bridge has priority 32768, address 0000.0c7f.70fc

Designated port id is 128.6, designated path cost 0

Timers: message age 0, forward delay 0, hold 0

Number of transitions to forwarding state: 1

BPDU: sent 1663, received 2

Port 8 (ATM0/0/0.235) of Bridge group 1 is forwarding

Port path cost 14, Port priority 128, Port Identifier 128.8.

Designated root has priority 32768, address 0000.0c7f.70fc

Designated bridge has priority 32768, address 0000.0c7f.70fc

Designated port id is 128.8, designated path cost 0

Timers: message age 0, forward delay 0, hold 0
