show iparp stats

show iparp stats [[vr_name | vr {all | vr_name} ] { no-refresh |refresh} {vr} summary]
show iparp stats [vlan {all {vr vr_name}} | [ {vlan} vlan_name | vlan vlan_list] {no-refresh |refresh}
show iparp stats ports {all | port_list} { no-refresh |refresh}

Description

Displays the IP ARP statistics for one or more VRs, VLANs, or ports.

Syntax Description

vr_name Specifies a VR or VRF for which to display statistics.
vlan_name Specifies a VLAN for which to display statistics.
vlan_list Specifies a VLAN list of IDs to display statistics.
refresh Continuous refresh of output.
port_list Specifies a list of ports for which to display statistics.

Default

Shows all VLAN ARP statistics in a dynamic display.

Usage Guidelines

VLAN statistics and totals are displayed for a single VR. When you display IPARP statistics for one or all VLANS, the display includes the specified VLANS for the specified VR. If you do not specify a VR for a VLAN report, the display includes the specified VLANS for the current VR context.

Periodically as part of cleanup, failed entries go down and hence the total entries goes down. In certain scenarios, they may help detect a problem ( memory leak or an attack). The show iparp stats command shows totals across all VRs, including VR-Mgmt.

Example

The following example displays ARP table statistics for all VRs and VRFs:
