Displaying IP configuration information and statistics
NOTE
The ip-mask parameter and mask parameter perform different operations. The ip-mask parameter
specifies the network mask for a specific IP address, whereas the mask parameter provides a filter
for displaying multiple MAC addresses that have specific values in common.
The num parameter lets you display the table beginning with a specific entry number.
NOTE
The entry numbers in the ARP cache are not related to the entry numbers for static ARP table entries.
This display shows the following information. The number in the left column of the CLI display is
the row number of the entry in the ARP cache. This number is not related to the number you assign
to static MAC entries in the static ARP table.
TABLE 18 CLI display of ARP cache
Field Description
Total number
of ARP
Entries The number of entries in the ARP cache.
Maximum
capacity The total number of ARP entries supported on the device.
IP Address The IP address of the device.
MAC Address The MAC address of the device.
Type The ARP entry type, which can be one of the following:
•
Dynamic – The Layer 3 Switch learned the entry from an incoming packet.
•
Static – The Layer 3 Switch loaded the entry from the static ARP table when the device for the
entry was connected to the Layer 3 Switch.
•
DHCP – The Layer 3 Switch learned the entry from the DHCP binding address table.
NOTE: If the type is DHCP, the port number will not be available until the entry gets resolved
through ARP.
Age The number of minutes before which the ARP entry was refreshed. If this value reaches the ARP
aging period, the entry is removed from the table.
To display the ARP aging period, refer to
“Displaying global IP configuration information” on
page 113. To change the ARP aging interval, refer to “Changing the ARP aging period” on page 37.
NOTE: Static entries do not age out.
Port The port on which the entry was learned.
NOTE: If the ARP entry type is DHCP, the port number will not be available until the entry gets
resolved through ARP.
Status The status of the entry, which can be one of the following:
•
Valid – This a valid ARP entry.
•
Pend – The ARP entry is not yet resolved.
