Determine Which SFP Is Installed in Your Cisco Line Module
May 8, 2008 by Greg Ferro · 4 Comments
This interface has a module installed.
lonrsw02#show inter gig6/2 capabilities GigabitEthernet6/2 Dot1x: yes Model: WS-X6724-SFP Type: 1000BaseSX Speed: 1000 Duplex: full Trunk encap. type: 802.1Q,ISL Trunk mode: on,off,desirable,nonegotiate Channel: yes Broadcast suppression: percentage(0-100) Flowcontrol: rx-(off,on,desired),tx-(off,on,desired) Membership: static Fast Start: yes QOS scheduling: rx-(1q8t), tx-(1p3q8t) CoS rewrite: yes ToS rewrite: yes Inline power: no SPAN: source/destination UDLD yes Link Debounce: yes Link Debounce Time: yes Ports on ASIC: 1-12 Port-Security: yes
This interface does not have the module installed.

Hi,
I’m a usual reader of your great blog… plenty of great posts!
Keep up with the good work
I just want to add something that maybe could help somebody out there, in case of a c76k with a ES20 card, we may use a great command that gives us a very detailed information, that already helped me in the past.
Here is an example:
—
c7609#sh hw-module subslot 9⁄0 transceiver 0 idprom
IDPROM for transceiver GigabitEthernet9/0/0:
Description = SFP optics (type 3)
Transceiver Type: = GE LX (20)
Product Indentifier (PID) = QFCT-5798LP
Vendor Revision =
Serial Number (SN) = AGT********6
Vendor Name = CISCO-AVAGO
Vendor OUI (IEEE company ID) = 00.17.6A (5994)
CLEI code = N/A
Cisco part number = N/A
Device State = Enabled.
Date code (yy/mm/dd) = 07÷01÷14
Connector type = LC.
Encoding = 8B10B
NRZ
Nominal bitrate = GE (1300 Mbits/s)
Minimum bit rate as % of nominal bit rate = not specified
Maximum bit rate as % of nominal bit rate = not specified

See you,
Tiago
Another command I find useful for this on newer code is “show inventory”. This includes SFPs and their serial numbers.
This worked, but the exact syntax that worked for me is below.
lonrsw02#show inventory raw | b 6⁄2
NAME: “Gigabit Port Container 6/2″, DESCR: “Gigabit Port Container”
PID: , VID: , SN:
NAME: “Gi6/2″, DESCR: “1000BaseSX”
PID: , VID: , SN: AGMaaaaaaGPG
How about my favorite command, “show interface status”?
Port Name Status Vlan Duplex Speed Type
Gi1/20 disabled routed full 1000 No Transceiver
Gi1/21 disabled routed full 1000 No Transceiver
Gi1/22 FW INSIDE connected 10 full 1000 1000BaseSX
Gi1/23 FW OUTSIDE connected 100 full 1000 1000BaseSX
