Please log in for more thread options but when I do "show interface", I only see two fastethernet interfaces and not the newly installed serial board. is there any extra setup i need to do to make it working? could it be faulty board? Thank you for your help -Thomas | |||||||||||||

Please log in for more thread options AFAIK NM-4T is not supported on 26xx see Cisco doc http://www.cisco.com/en/US/products/hw/routers/ps274/products_tech_note09186a00800a93f3.shtml#topic3 I believe only the 1-port or 2-port T1 WIC's are supported on 26xx | |||||||||||||

I wanted to use that 2621 router as frame relay cloud for my lab. Can I use the 4 port async serial port then? Thank you again -Thomas | |||||||||||||

WIC-1T/WIC-2T are supported. And are very cheap. >I wanted to use that 2621 router as frame relay cloud for my lab.
Weren't you the one that had the 3620 that was going to do the NM-4AS? Or was that somebody else? >Can I use the 4 port async serial port then?
Err, I wouldn't recommend it, Frame-Relay really wants to use the synch serial ports. | |||||||||||||

Unless of course I decide than Dynamips will do the job for me. I do have a lot of Cisco hands on so I think I will get away with it. Merv of course means wic-1t and wic-2t. http://www.cisco.com/en/US/products/hw/routers/ps274/products_tech_note09186= a00800b0858.shtml WIC...T1 is something a bit different:-) | |||||||||||||
