Hi to all,
I have a 2960XR with 48 Gigabyte port and 2x SFP+ port (Level 3 Switch)
This is probably a stupid question for those who are familiar with Cisco hardware but when looking at the configuration i see 4 SFP+ interface.
Example :
When i type show vlan... i see Te1/0/1, Te1/0/2, Te1/1/1 and Te1/1/1
VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Te1/1/1, Te1/1/2 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup 2000 GUEST_LAN active Gi1/0/5, Gi1/0/6, Gi1/0/7 Gi1/0/8, Gi1/0/9, Gi1/0/10 Gi1/0/11, Gi1/0/12, Gi1/0/13 Gi1/0/14, Gi1/0/15, Gi1/0/16 Gi1/0/17, Gi1/0/18, Gi1/0/19 Gi1/0/20, Gi1/0/21, Gi1/0/22 Gi1/0/23, Gi1/0/24, Gi1/0/25 Gi1/0/26, Gi1/0/27, Gi1/0/28 Gi1/0/29, Gi1/0/30, Gi1/0/31 Gi1/0/32, Gi1/0/33, Gi1/0/34 Gi1/0/35, Gi1/0/36, Gi1/0/37 Gi1/0/38, Gi1/0/39, Gi1/0/40 Gi1/0/41, Gi1/0/42, Gi1/0/43 Gi1/0/44, Gi1/0/45, Gi1/0/46 Gi1/0/47, Gi1/0/48, Te1/0/1 3000 WIFI active Gi1/0/1, Gi1/0/2, Gi1/0/3 Gi1/0/4, Te1/0/2
When i type show ip interface brief... i see only two SFP+ inteface but port 49 and 50 (but it's a 48 port switch)

Is it normal ?
How to setup my two SFP Port properly ? what are the good information ?
Best Regards.

2960XR has different models. Can you share "show version" to see which platform are you using?

It could be because they use the same software for all different models and so, in your case, you have 2 10Gig uplinks. And as long as your 2 10Gig ports work fine, you should be ok. If you want, you can always open a ticket with TAC to make sure this is not a bug.

Is it normal ? Yes.
How to setup my two SFP Port properly ? If you install the 10G SFP you will configure the Te1/0/1, if you install 1G you will configure the G1/0/49.
I guess this why the port are repated.
thanks
