What's the diff between a line being "down" and "administratively down" ?
|
|
|
| When using the "show int" command, what's the diff between the above two outputs?
Cheers,

|
| I tried command "sh int" and
when I go thru for example:
int s 0
ip address ... .....
NO SHUT
it shows line is down
when I use
SHUT
it shows line is administratively down
| |
|
| I think "line is down" can possibly mean a cabling or interface prob, and "line is administratively down" means that an administrator has shut the line down. I think that to start with you have "line is down."
Not sure, though.

| you are right!
if there are more than one administrators,
who access one router, it's nice to see,
if a line is accidently down or another admin wants the line to be down...

| With line down it could be serveral problems.
1. Protocols do not match between routers. Example: if one router is configured with HDLC encap and the other is PPP encap the line will show Line down; Protocol down.
2. There is an internal problem communicating between your LAN and router.
Administrative Shutdown is just that... This line was shutdown by an administrator.
Are you using real routers or a simulator? I have never seen what you are talking about. Then again I never used a shutdown command by itself. I will have to try...

| Here is a copy and paste from an actual router:Serial4/1/21:0 is administratively down, line protocol is down
Hardware is PA-MC-2T3+
Description: AC: Brooks America T1 - PB 81hcre961583-001pt LOCKED 10/10/2000 VB 226854
Notice the description says "LOCKED". This is a customer who hasn't payed their bill. The interface is administratively shut down. | |
|
| I've shut loads down as well as have lines go down on me. This is just to confirm what's been written.
administratively down means the interface has been shutdown by the administrator.
Line down means the line has gone down
Protocol down can be a few things like wrong subnet, but if the line is up but the protocol is down it means the cables are all in and the router can see something at the other end.
Cheers
Kevin.
