Displaying IP information
19
The mac-address xxxx.xxxx.xxxx parameter lets you restrict the display to entries for a specific MAC
address.
The mask parameter lets you specify a mask for the mac-address xxxx.xxxx.xxxx parameter to
display entries for multiple MAC addresses. Specify the MAC address mask as fs and 0s, where fs
are significant bits.
The ip-addr and ip-mask parameters let you restrict the display to entries for a specific IP address
and network mask. Specify the IP address masks in standard decimal mask format (for example,
255.255.0.0).
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 address entries in the static ARP table.
TABLE 104 CLI display of ARP cache
This field... Displays...
IP Address The IP address of the device.
MAC Address The MAC address of the device.
Type The type, which can be one of the following:
•
Dynamic – The Brocade device learned the entry from an incoming
packet.
•
Static – The Brocade device loaded the entry from the static ARP table
when the device for the entry was connected to the Brocade device.
•
Pending – The Brocade device added the entry to the ARP table and is in
the process of sending a series of ARP requests to determine if it is a valid
entry.
Age The number of minutes the entry has remained unused. 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” . To change the ARP aging interval, refer to “Changing the ARP
aging period” .
NOTE: Static entries do not age out.
Port The port on which the entry was learned.
