Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname Router1
Router1(config)#interface eth0
Router1(config-if)#ip address 192.168.1.1 255.255.255.0
Router1(config-if)#no shutdown
%LINK-3-UPDOWN: Interface Ethernet0, changed state to up
Router1(config-if)#exit
Router1(config)#interface serial0
Router1(config-if)#ip address 192.168.2.1 255.255.255.0
Router1(config-if)#no shutdown
%LINK-3-UPDOWN: Interface Serial0, changed state to up
Router1(config-if)#exit
Router1(config)#exit
%LINK-3-UPDOWN: Interface Serial0, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down
Router1#show ip interface brief
Interface IP-Address OK? Method Status Protocol
Serial0 192.168.2.1 YES unset up down
Serial1 unassigned YES unset administratively down down
Ethernet0 192.168.1.1 YES unset up up
Ethernet1 unassigned YES unset administratively down down
Bri0 unassigned YES unset administratively down down
Bri0:1 unassigned YES unset administratively down down
Bri0:2 unassigned YES unset administratively down down
This only seems to happen on the router which has a Ethernet and a Serial. On the router that is just Serial, this does not happen.
Bug in the software? |
Looks to me like there's a mismatched encapsulation on both ends if it was a real scenario.
Could you put down if there is more than 1 router involved in this?
