IPv4 Interface
Command Mode
Interface Configuration (VLAN)
Command Usage
• Proxy ARP allows a non-routing device to determine the MAC address of a host on another
subnet or network.
• End stations that require Proxy ARP must view the entire network as a single network. These
nodes must therefore use a smaller subnet mask than that used by the router or other relevant
network devices.
• Extensive use of Proxy ARP can degrade router performance because it may lead to increased
ARP traffic and increased search time for larger ARP address tables.
Example
Console(config)#interface vlan 3
Console(config-if)#ip proxy-arp
Console(config-if)#
clear arp-cache
This command deletes all dynamic entries from the Address Resolution Protocol (ARP) cache.
Command Mode
Privileged Exec
Example
This example clears all dynamic entries in the ARP cache.
Console#clear arp-cache
This operation will delete all the dynamic entries in ARP Cache.
Are you sure to continue this operation (y/n)?y
Console#
show arp
This command displays entries in the Address Resolution Protocol (ARP) cache.
Command Mode
Normal Exec, Privileged Exec
Command Usage
• This command displays information about the ARP cache. The first line shows the cache
timeout. It also shows each cache entry, including the IP address, MAC address, type (dynamic,
other), and VLAN interface. Note that entry type “other” indicates local addresses for this
router.
• Static entries are only displayed by this command for VLANs that are up. In other words, static
entries are only displayed when configured for the IP subnet of a existing VLAN, and that VLAN
is linked up.
Example
This example displays all entries in the ARP cache.
Console#show arp
