Viewing STP statistics
You can view a summary of STP statistics for Layer 2 Switches and Layer 3 Switches. STP statistics
are by default polled every 10 seconds.
To view spanning tree statistics, enter the show span command. To view STP statistics for a VLAN,
enter the span vlan command.
Clearing statistics
You can clear statistics for many parameters using the clear command.
To determine the available clear commands for the system, enter the clear command at the Privileged
EXEC level of the CLI.
device#clear ?
Syntax: clear option
You also can enter "clear" at the command prompt, then press the TAB key.
Traffic counters for outbound traffic
You can configure traffic counters (also called transmit counters) that enable the Brocade device to
count the following packet types on a port or port region:
• broadcast packets
• multicast packets
• unicast packets
• dropped packets due to congestion and egress filtering
Depending on the parameters specified with the traffic counter configuration, traffic counters record
the number of outbound packets from any combination of the following sources:
• a specific port or all ports in a specific port region
• a specific VLAN or all VLANs
• a specific 802.1p priority queue or all priority queues
