Cabletron Systems EMM-E6 Ethernet Manual De Usuario

The following provides a brief description, the proper format, and an 
example of each Built-In command.

The arp command provides access to the ARP (Address 
Resolution Protocol) cache, enabling you to view cache 
data, delete entries, or add a static route. Superuser access 
is required to delete an entry or add a static route.

Each arp cache entry lists: the network 

interface that the 

device is connected to, the device’s

 network address or IP 

address, the device’s 

physical address or MAC address, and 

the 

media type of connection to the device. The device’s 

media connection occurs in one of the following ways:

1 - Other
2 - Invalid entry (cannot ping device, timed out, etc.)
3 - Dynamic route entry
4 - Static route entry (not subject to change).

Format

arp -a (to view cache data)

arp -d <INTERFACENUM> 
<IPADDRESS> (deletes an IP address 
entry)
arp -s <INTERFACENUM> 
<IPADDRESS> <MACADDR>

 (adds a 

static entry)

Example

   MIBNav>

 arp -a

# Interface   Network Address  Physical Address  Media Type
