Why we see interface TenGigabitEthernet1/1/1 ?

[soztekin@hotmail.com]

Hello All 

When i enter " show  runnig-configuration "  in Cisco 3850 Switch i see interfaces through interface TenGigabitEthernet1/1/1 - 1/1/16 but there are no ports like that. Port numbers are 1/0/1-48 and 2/0/1-48.

Thanks

any "middle" number (y) means module in x/y/z; those are fiber uplink modules and standard low end 3850 switch supports 4 x 1 Gigabit and  4 x 10 Gigabit.

I noticed that too; c3850s have 10 Gig ports listed in config even thou there might be no such module inserted.

Use sh inter status command to get the right output

Hello

The switch can support either 1 or 10gb sfps in the same module slot so the ios will show 1/10 gb interfaces in the running configuraton for the same physcal slot.

For example:
Same Physical slot
int gig1/1/1/  < 1GB
int te1/1/1  < -10gb
