Neighbor name not matching the actual device name

[Unique-11]

I have a L2 switch( let say Switch A ) and it's connected to another switch ( Switch B )

when I do show cdp neiboor from switch B it showing me the switch name which is SwitchA + another word

The qouestion is : I need to know why there is another word appering beside the actual switch name ? and how can I remove i ?

I've seen similar issue before. 

Try:

- Change the hostname

- waited for the holdtime timer to expire

- change the hostname again

You can also disable CDP , change hostname , re-enable CDP

Hello,

is that just a random word being tagged on to the actual hostname, or does it correspond to something you see in the output of 'show cdp neighbor detail' ?

One instance where e.g. the domain name would be appended is when you have 'ip domain-lookup' and 'ip domain-name x' configured on the switch...
