Complete

Displays a snapshot or real-time histogram of packet statistics.

Syntax Description

mgmt Specifies the management port.
port_list Specifies one or more ports or slots and ports.
tag Specifies an 802.1Q or 802.1ad tag value.
no-refresh Specifies a static snapshot of data.
refresh Specifies a continuous refresh of output.

Real-time statistics.

Usage Guidelines

If you do not specify a port number, range of ports, or tag value, the system displays information for all ports; if you specify the no-refresh parameter, the system displays a snapshot of the data at the time you issue the command. To clear the counters, use the clear counters ports command.

The tag value may be associated with either a VMAN or a VLAN (Virtual LAN).

This status information may be useful for your technical support representative if you have a network problem.

The following packet statistics are displayed:

  • Port number
  • Link state
  • Packet size

Example

The following command displays packet statistics ports 1 through 8 on a switch:
