Configuring L3 Aggregate Ports 
This section deals with how to create an L3 aggregate port and some related configuration. 
In the interface configuratiion mode, you can use the no switchport command to convert a L2 
aggregate port to a L3 aggregate port: 
Ruijie(config-if)# no switchport 
Shut  down  the  interface  and 
change it to L3 mode. 
Ruijie(config-if)# ip address ip_address 
subnet_mask 
Configure  the  IP  address  and 
subnet mask. 
The following example shows how to create an L3 aggregate port and assign an IP address to 
it. 
Ruijie# configure terminal 
Enter configuration commands, one per line. End with CNTL/Z. 
Ruijie(config)# interface aggregateport 2 
Ruijie(config-if)# no switchport 
Ruijie(config-if)# ip address 192.168.1.1 255.255.255.0 
Ruijie(config-if)# no shutdown 
Ruijie(config-if)# end 
Showing Interface Configuration and Status 
This section covers interface status display and gives examples. You may view interface status 
by using the show command in the privileged EXEC mode. To show interface status, use the 
following commands. 
Ruijie# show interfaces [interface-id] 
Show  the  status  and 
configuration  of  the  specified 
interface. 
Ruijie# show interfaces interface-id status   
Show the status  of  the specified 
interface. 
Ruijie#  show  interfaces  [interface-id] 
switchport 
Show  the  administrative  and 
operational  status  of  an  switch 
interface (non-routing interface). 
Ruijie#  show  interfaces  [interface-id] 
description 
Show  the  description  and  status 
of the specified interface. 
Ruijie# show interfaces [interface-id] counters 
Show  the  statistics  of  the 
specified port. 
Where,  the  rate  displayed  may 
have an error of less than 0.5%. 
The following example shows how to display the status of Gigabitethernet 1/1.
