router problem

Hi guy!

I have a real big problem with a lab router i just bought for my lab 2610xm. I would really need an advice to solve this problem.

1.The F0/0 interface when plugged into the 2950 switch i have come on alive and on the switch, it would show the status and protocol from down down to up up but when i do a "SH CDP N" in the switch it wouldn't see the router but would see my second switch. Now i went into the switch hard code the interface i have the router connected to "Duplex Full, Speed 100" also played around making the switch port to be in AUTO, DYNAMIC and all there is to seeing if the switch would see the router when i do a CDP command. But to no avail.

2. The said router, doesn't support ENCAPSULATION try to encaps it for 802.1q protocol it doesn't work. Gone through the contest help didn't seen ENCAPSULATION as one of the supported command.

I am actually having a feeling that it has to do with the IOS! fine this below as i did the SHOW VERSION command.

Any advice to this would be appreciated as to solving this problem please.... i need for ma router to come back to life!

To see the encapsulation command you have to be in a sub-interface:

Router(config)#int fa 0/0.1
Router(config-subif)#?
Interface configuration commands:
arp Set arp type (arpa, probe, snap) or timeout
backup Modify backup parameters
bandwidth Set bandwidth informational parameter
bgp-policy Apply policy propagated by bgp community string
bridge-group Transparent bridging interface parameters
cdp CDP interface subcommands
crypto Encryption/Decryption commands
default Set a command to its defaults
delay Specify interface throughput delay
description Interface specific description
dlsw DLSw interface subcommands
dspu Down Stream PU
encapsulation Set encapsulation type for an interface
exit Exit from interface configuration mode
fras DLC Switch Interface Command
h323-gateway Configure H323 Gateway
ip Interface Internet Protocol config commands
ipv6 IPv6 interface subcommands
keepalive Enable keepalive
llc2 LLC2 Interface Subcommands
mtu Set the interface Maximum Transmission Unit (MTU)
--More--

I know encapsulations are for subinterfaces, but still not working. I created the sub interface and tried doing the encapuslation command......didn't work. I want to believe that the IOS i have on the router doesn't support it!!!

You need IP Plus or better for 802.1q. You only have IP Base.

Do you mean IP Based IOS? And if it is!!! can i download it off from Cisco's site or if you have a url were i could download it from i would really appreciate it alot! thanks!

No. IOS has several feature sets which define which features it supports. IP Base is the lowest.

You need a SMARTnet support contract assigned to your CCO account at cisco.com to download.

Good posts. Thanks for the heads up.

I have the same issue with an old 2600 router I am using with the CCNA study curriculum. I am trying to configure "router on a stick" and the encapsulation command isn't available under the sub interface. The flash is an older version (flash:c2600-i-mz.123-26.bin). I have tried to upload an IOS that I copied from another router (c2600-jk8o3s-mz.122-12a.bin) via a TFTP server but I don't have enough memory in my router to do so and it errors out.
Since it appears that the sub interfaces will configure on this router does anyone know if there is an older pre-encapsulation dot1q command I can use for practicing the router on a stick configuration?
