2600 Router as Terminal/Serial Server and Access Points

Hi Guys,

I have set myself up my lab with a 2600 router acting as a Terminal/Serial server to connect to all of my devices. (using a NM-16A etc)

I seem to have a problem when connecting to any access point.

I can connect to a switch, wireless controller and location appliance no problem but just not an access point.

If i connect my PC using a standard blue CLI cable to an access point it connects fine.

Does anyone know if there is any special configuration that i need to make on my terminal server just for the access points?

My config:

version 12.2
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
hostname serial-server
enable secret 5 $1$2O5U$LunUrjzhSlPmoG6nCNU9l0
username Cisco password 0 Cisco

Any advice would be great

Re: 2600 Router as Terminal/Serial Server and Access Points

are the APs in LWAPP mode?? or Autonomous?? if its LWAPP APs have you enabled Telnet on the WLC (By default Telnet is disabled on LWAPP APs i guess)??

the command is

(Cisco Controller) >config ap telnet enable {Works only when the AP is registered to the WLC}

if the AP name is 1131AP then the example will be..

(Cisco Controller) >config ap telnet enable 1131AP

if its Autonomous.. then please check whether Telnet is allowed or not..

AP >> Services >> TELENT/SSH >> Enable (Telnet).

Lemme know how this works out for you!!



Re: 2600 Router as Terminal/Serial Server and Access Points


many thanks for your reply.  Am not actually tying to telnet onto these devices.

I have a 2600 router with a NM-16a Serial card and telnet onto the router which then creates a serial connection to the device on one of the 16 serial ports.

As mentioned this is all working fine for network switches, WLC's but not just for AP's.  I was not sure if there was a special bit rate,parity etc that i need to config.

If i connect directly from a PC to any of the AP's with the standard Cisco CLI cable all is fine.

Need to get this working as i have 9 access points that i am trying to config.

any help is appreciated
