The following troubleshooting commands are executed from the CLI: 

user1 # get system interface 

== [ internal ] 

namE. internal modE. static ip: 10.0.1.254 255.255.255.128 status: up 

netbios-forwarD. disable typE. physical mtu-overridE. disable 

== [ vlan1 ] 

namE. vlan1 modE. static ip: 10.0.1.1 255.255.255.128 status: up netb 

ios-forwarD. disable typE. vlan mtu-overridE. disable

Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP 

O - OSPF, IA - OSPF inter area 

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 

E1 - OSPF external type 1, E2 - OSPF external type 2 

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
