I am documenting equipment which requires me to state installed Physical Layer Interface Module (PLIM)/slot and transceivers/interfaces. What confused me is the different information shown between #show inventory
and #show interface description
.
-
The information from
#show interface description
doesn't list all interfaces under a slot shown from#show inventory
. The slot has status ready from#show platform
. -
The information from
#show inventory
doesn't list all interfaces which are listed from#show int description
.
Any reasons for these situations? Any suggestions so that I can documenting without any contradictions? Router is Cisco ASR 12000 series.
Best Answer
show inventory
shows you the device components, part-no. and erial-no. so you may also see controllerĀ“s, Crypto-Modules, SFP's, Power-supplies, etc.show interface
shows all interfaces (which may have a protocal attached, for example, IPv4) . This includes interfaces without hardware, like loopback, tunnel, Ethernet.subinterfaces ( gig 0/1.234 ) , and dynamically created (virtual-access, ...) or the stamp of them (virtual-template).Use "show inventory" "show license" "show hardware" "show diag" "show platform" to collect the physical infrastructure.
Get "show running" for the Configuration and the allways-be-there interfaces, including non-physical or interface-templates.
Dont forget to save the IOS Version and Variety which is running.
