Hi Ezra,

 

Only the default keepalives

No configuration of keepalives is done on this interface.

 

Thank you

Do you have keepalives set on that interface?

Hi All,

 

I have a Cisco 1751 running IOS c1700-k9o3sy7-mz.124-1.bin.

When we removed the cable from the interface and check the interface it
status still shows up.

I can ping the interface but not the device connected to it.

 

Has someone seen this problem before?

 

Before I shutdown the interface 

Goast#sh ip int b

Interface                  IP-Address              OK? Method Status
Protocol

Ethernet1/0                xxx.xxx.xxx.xxx    YES NVRAM  up
up      

Loopback0                  xxx.xxx.xxx.xxx    YES NVRAM  up
up      

Goast#sh run

 

After the interface was shutdown

Goast#sh ip int e1/0

Ethernet1/0 is administratively down, line protocol is down
