• show iparp—Displays the IP ARP table of the system. On a stacked set of switches, this command
displays the statistics for the master switch and for the IP ARP table of member switches by
redirecting the console output through the master switch.
• show iparp stats—Displays the IP ARP statistics for member switches of a stack from the stack
master.
• show ipfdb—Displays the hosts that have been transmitting or receiving packets, and the port and
VLAN for each host. On a set of stacked switches, this command displays the member switches
information.
• show ipconfig—Displays configuration information for one or more VLANs.
IP Commands
Table 55 describes the commands used to configure basic IP settings.
Table 55: Basic IP Commands
Command Description
clear iparp {<ipaddress> <mask> | vlan <vlan>} Removes dynamic entries in the IP ARP
table. Permanent IP ARP entries are not
affected.
clear ipfdb {<ipaddress> <netmask> | vlan <name>} Removes the dynamic entries in the IP
forwarding database. If no options are
specified, all dynamic IP FDB entries are
removed.
config bootprelay add <ipaddress> Adds the IP destination address to forward
BOOTP packets.
config bootprelay delete [<ipaddress> | all] Removes one or all IP destination
addresses for forwarding BOOTP packets.
config iparp add <ipaddress> <mac_address> Adds a permanent entry to the ARP table.
Specify the IP address and MAC address
of the entry.
config iparp add proxy <ipaddress> {<mask>}
{<mac_address>} {always}
Configures proxy ARP entries. When mask
is not specified, an address with the mask
255.255.255.255 is assumed. When
mac_address is not specified, the MAC
address of the switch is used in the ARP
Response. When always is specified, the
switch answers ARP Requests without
filtering requests that belong to the same
subnet of the receiving router interface.
config iparp delete <ipaddress> Deletes an entry from the ARP table.
Specify the IP address of the entry.
config iparp delete proxy [<ipaddress> {<mask>} |
all]
Deletes one or all proxy ARP entries.
config iparp timeout <minutes> Configures the IP ARP timeout period. The
default setting is 20 minutes. A setting of 0
disables ARP aging. The maximum aging
time is 32,767 minutes.
