Use DNS server with 192.168.16.35 and 192.168.16.38 addresses, define the default domain name
mes :
сonsole# configure
console(config)# ip name-server 192.168.16.35 192.168.16.38
console(config)# ip domain-name eltex-sw-1
Define static match: network node with the name eltex.mes has IP address 192.168.16.39:
сonsole# configure
console(config)# ip host eltex.mes 192.168.16.39
5.16.2 ARP protocol configuration
ARP (Address Resolution Protocol) is a channel-level interface that performs the identification of
MAC address based on the IP address contained in the request.
Global configuration mode commands
Command line request in global configuration mode appears as follows:
console(config)#
Table 5.69 —Global configuration mode commands
Command Value/Default value Action
arp ip_address
mac_address
[gigabitethernet gi_port |
fastethernet fa_port |
port-channel group |
vlan vlan_id ]
ip_address format: A.B.C.D
mac_address format:
H.H.H
H:H:H:H:H:H
H-H-H-H-H-H;
gi_port: (1..3/0/1..28);
fa_port: (1..3/0/1..24);
group: (1..8);
vlan_id: (1..4094)
Add the static record of matches between IP and MAC
addresses to ARP table for the interface, specified in the
command.
- ip_address —IP address
- mac_address —MAC address
no arp ip_address
[gigabitethernet gi_port |
fastethernet fa_port |
port-channel group |
vlan vlan_id ]
Remove the static record of matches between IP and MAC
addresses from ARP table for the interface, specified in the
command.
arp timeout seconds
seconds: (1-40000000)/
60000 seconds
