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
Traffic counters configuration notes
Consider the following rules when configuring traffic counters for outbound traffic.
• This feature is supported on FastIron X Series devices only.
• This feature is supported in the Layer 2 and Layer 3 codes.
• This feature applies to physical ports only, including 10 Gbps Ethernet ports and trunk ports. It does
not apply to virtual interfaces.
• Once the enhanced traffic counters are read using the
show transmit-counter values
command,
the counters are cleared (reset to zero).
• For each port region, you can enable a maximum of two traffic counters, regardless of whether
traffic counters are enabled on individual ports or on all ports in the port region.
• Traffic counters increase for bridged filtered outbound traffic when any of the following conditions
occur:
‐
The port is disabled or the link is down.
‐
The port or port region does not belong to the VLAN specified in the transmit counter
configuration.
‐
A Layer 2 protocol (e.g., spanning tree) has the port in a Blocked state.
‐
The source port needs to be suppressed for multi-target packets.
‐
The priority queue specified in the traffic counter is not allowed for some other reason.
‐
Unknown unicast and unregistered multicast packets are filtered.
Traffic counters configuration syntax
This section provides the syntax and configuration examples for enhanced traffic counters.
To configure traffic counters for outbound traffic on a specific port, enter a command such as the
following.
device(config)#transmit-counter 4 port 18 only vlan 1 prio 7 enable
The above command creates and enables traffic counter 4 on port 18. The device will count the
number of packets sent out on port 18 that are in VLAN 1 and have a priority queue of 7.
