"show version" interpretation

rc5295509 · ‎03-26-2012

Hello

I have a doub, I change only a chasis in a router 3845, but the "show version" command should be the same , except for the serial number and other parameter of time.. however, the number of serial interface change from 4 up to 2.. you know what is the reason?

The hardware module of 3845 are 3.

1.- VWIC E1/T1 with 2 port

2.- Fastethernet 36 port

3.- Supervisor engine with 2 Gigabit port

Cisco 3845 (revision 1.0) with 483328K/40960K bytes of memory.

Processor board ID FTX1131A14P--à New Chassis

36 FastEthernet interfaces

2 Gigabit Ethernet interfaces

2 Serial interfaces--à 2 Serial IF

2 Channelized E1/PRI ports

1 Virtual Private Network (VPN) Module

DRAM configuration is 64 bits wide with parity enabled.

479K bytes of NVRAM.

125440K bytes of ATA System CompactFlash (Read/Write)

Configuration register is 0x2102

hi rodrigo,

try using the show inventory or show diag commands instead to view installed network modules on your 3845.

I wonder if the router has some type of WIC card for the serial interfaces which requires the card type and controller configuration to create the serial interfaces and if the card might have been in a different slot or something that would make the original configuration invalid in the new chassis. I agree with John that show inventory or show diag would be a good way to begin to investigate this.

Hi..

Well, I dont see serial port with de module.. this is the show inventory... with show diag.. is the same.. The version is 12.4.(15)T5,

Rodrigo

Thank you for the output of show inventory. While it does not provide the clear answer that I had hoped, it may point us toward something to investigate.

It clearly shows that there is a single VWIC with 2 ports. So I begin to wonder - how do you get 4 serial interfaces when there is only a 2 port VWIC? I would assume that there was something in the configuration that creates several serial interfaces on a single port of the VWIC. What was that configuration and did it possibly change when you moved to the new chassis?

So can you post the configuration of the 3845 when it had 4 serial interfaces and the configuration of the current 3845 which has only 2?

Thank you for posting the configs. But they still leave me confused about this issue. Each config seems to have the same configured two serial controllers and only a single serial interface. So I am quite puzzled how the show version indicated 4 serial interfaces.

From a configuration perspective it looks like both chassis have exactly the same amount of interfaces. I wonder if there might have been something configured, or some card inserted which was reflected in show version of the old chassis but is not present in the new chassis.

Hi Rick

Well, I think that is a missundertanding of a IOS. is a very old version.. but Nonetheless in the configuration appear one serial interface, that belong to E1 chanelized. for other way ¿could be a software bug?

Rodrigo
