In this post we explain how to configure interfaces on Cisco, Juniper and Alcatel-Lucent
Cisco
Interface Configuration:
In Cisco we use physical interfaces to configure the IP address
Cisco-RTR#sh run interface gigabitEthernet 2/2/20
Building configuration...
Current configuration : 95 bytes
!
interface GigabitEthernet1/9
ip address 10.10.10.1 255.255.255.252
end
Juniper
Interface Configuration:
In Juniper we always configure IP address in logical interface.
lab@juniper#set interfaces ge-2/2/20 unit 0 family inet address 10.10.10.1/30
lab@Juniper> show configuration interfaces ge-2/2/20
unit 0 {
family inet {
address 10.10.10.1/30;
}
}
Alcatel-Lucent
Interface configuration:
Alcatel-Lucent 7750 SR router ports must be configured as either access, hybrid or network. The default is network.
· Access ports — Customer facing ports on which services are configured
· Network ports —Network facing ports.
· Hybrid ports — Configured for access and network facing traffic.
Configuring interface in Alcatel is different when compared with Juniper and Cisco. Interface is completely logical entity in Alcatel-Lucent.
Configure Port Properties:
ALU-RTR#
configure port 2/2/20 ethernet mtu 1500
ALU-RTR# configure port 2/2/20 no shutdown
To view configuration on port go into configure port 2/2/20 hierarchy and enter info
ALU-RTR>config>port# info
----------------------------------------------
ethernet
mtu 1500
exit
no shutdown
----------------------------------------------
ALU-RTR>config>port#
Interface Configuration:
For interface we have to give the name .To Configure Interface enter following commands:
ALU-RTR# configure router interface <INTERFACE-NAME> address 10.10.10.1/30
ALU-RTR# configure router interface <INTERFACE-NAME> port 2/2/20
ALU-RTR# configure router interface <INTERFACE-NAME> no shutdown
To view configuration on interface go into configure router interface <INTERFACE-NAME> hierarchy and enter info
ALU-RTR>config>router>if# info
---------------------------------------------
address 10.10.10.1/30
port 2/2/20
no shutdown
----------------------------------------------
ALU-RTR>config>router>if#
great!!
