spanning-tree mode pvst command

Hello, I just noticed on a router configuration the the command "spanning-tree mode pvst" has been entered.

Is there any reason why a router would require this command in it's config file or is it just a mistake that it is there.

Thanks.

What model router do you have? Can you send a show version and show inventory? Most likely you have a switching module installed in it.

Hello, thanks for helping.

It is actually a packet tracer simulation.

A 'show version' reveals:

Cisco IOS Software, 1841 Software (C1841-ADVIPSERVICESK9-M), Version 12.4(15)T1, RELEASE SOFTWARE (fc2)

Technical Support: http://www.cisco.com/techsupport

Compiled Wed 18-Jul-07 04:52 by pt_team

Cisco 1841 (revision 5.0) with 114688K/16384K bytes of memory.

Processor board ID FTX0947Z18E

M860 processor: part number 0, mask 49

2 FastEthernet/IEEE 802.3 interface(s)

2 Low-speed serial(sync/async) network interface(s)

191K bytes of NVRAM.

63488K bytes of ATA CompactFlash (Read/Write)

The command "show inventory" does not work in packet traver.

Based on the above, should I leave the config entry "spanning-tree mode pvst" on the router or delete it ?

Thanks for any advice.
