Statistics commands

Introduction

You can view switch performance statistics in the user, operator, and administrator command modes. This chapter discusses how to use the ISCLI to display switch statistics.

The following table describes general Statistics commands.

Table 30 Statistics commands

Command	Usage
show layer2 counters	Displays Layer 2 Statistics.
	Command mode: All
show layer3 counters	Displays Layer 3 Statistics.
	Command mode: All
show snmp-server counters	Displays SNMP statistics.
	Command mode: All
show ntp counters	Displays Network Time Protocol (NTP) Statistics.
	You can execute the clear command option to delete all
	statistics.
	Command mode: All
show ufd counters	Displays Uplink Failure Detection statistics.
	Command mode: All
show counters	Dumps all switch statistics. Use this command to gather data for
	tuning and debugging switch performance. If you want to capture
	dump data to a file, set your communication software on your
	workstation to capture session data prior to issuing the dump
	command.
	Command mode: All

Port Statistics

The following table describes the Port Statistics commands. The following sections provide more detailed information and commands.

Table 31 Port Statistics commands

Command	Usage
show interface gigabitethernet	Displays bridging (“dot1”) statistics for the port.
<port number> bridging-counters	Command mode: All
show interface gigabitethernet	Displays Ethernet (“dot3”) statistics for the port.
<port number> ethernet-counters	Command mode: All
show interface gigabitethernet	Displays interface statistics for the port.
<port number> interface-counters	Command mode: All
show interface gigabitethernet	Displays Internet Protocol statistics for the port.
<port number> ip-counters	Command mode: All
show interface gigabitethernet	Displays link statistics for the port.
<port number> link-counters	Command mode: All
