Problem Programming Catalyst 2960x

[PNKTech1]

I'm encountering a problem getting a Cisco 2960x to accept a line of programming. I'm setting it up currently:

Switch#config t

switch(config)#hostname 3560_10

3560_10(config)#enable secret zxcvbnm

3560_10(config)#enable password cisco

3560_10(config)#line con 0

3560_10(config-line)#password cisco

3560_10(config-line)#login

3560_10(config-line)#exit

3560_10(config)#line vty 0 4

3560_10(config-line)#password cisco

3560_10(config-line)#login

3560_10(config-line)#exit

3560_10(config)#line vty 5 15

3560_10(config-line)#password cisco

3560_10(config-line)#login

3560_10(config-line)#exit

3560_10(config)#service password-encryption

3560_10(config)#vlan 10

3560_10(config-vlan)#name Surveillus

3560_10(config-vlan)#exit

3560_10(config)#interface vlan 1

3560_10(config-if)#ip address 10.20.85.20 255.255.0.0

3560_10(config-if)#no shutdown

3560_10(config-if)#exit

3560_10(config)#spanning-tree mode pvst

3560_10(config)#interface port-channel10

3560_10(config-if)#switchport mode trunk

3560_10(config-if)#exit

3560_10(config)#interface range gigabitethernet0/1 - 48

                                                                               ^                                                              

% Invalid input detected at '^' marker.

3560_10(config-if-range)#switchport access vlan 10

3560_10(config-if-range)#switchport mode access

3560_10(config-if-range)#spanning-tree portfast

3560_10(config-if-range)#exit

3560_10(config)#interface range gigabitethernet0/49 - 52

3560_10(config-if-range)#switchport mode trunk

3560_10(config-if-range)#exit

3560_10(config)#interface range gigabitethernet0/51 - 52

3560_10(config-if-range)#channel-group 10 mode active

3560_10(config-if-range)#end

3560_10#clock set 09:50:00 26 dec 2017

3560_10#wr mem

The line in bold is the one that won't take. The error arrow is pointing to the 0 in case formatting sets it off. Not sure why it won't take the command. Any useful advice would be much appreciated.

Thank you!

first thought was whether the switch was in a stack -   are all the ports set with the same properties? for range to work all the ports have to have the same base config.  might trigger a thought from another. watching.

[PNKTech1]

The switch is not in a stack, but the 3750's that are next in the chain are, but I don't think that matters does it?

[Joseph W. Doherty]

Hmm, looks right - i.e. one would expect it to work. What's the IOS image?

For ha ha's sake, you might also try "int range g0/1 - 48" or "int range g 0/1 - 48".

BTW
for:
spanning-tree mode pvst
I would recommend you use:
spanning-tree mode rapid-pvst

also rather for access interfaces':
spanning-tree portfast
you might use instead (global):
spanning-tree portfast default
spanning-tree portfast bpduguard default

It looks like you might be missing some part of the interface identifier, if you do a sho int status it should give you the correct format for your interface numbers in the port column.

For the 2960x switches we have deployed interfaces are listed as X/0/1-48 with X being the switch number in the stack which starts at 1.

If you have just the one switch the correct command should be

int range gigabitEthernet 1/0/1-48

[burleyman]

Ben is correct.

The command for a single switch would be...

int range gi1/0/1 - 48

[Joseph W. Doherty]

Ben and Mike, yea a switch number on the interface would make sense except for OP showing range g0/49 - 52 and g0/51 - 52 appeared to have been accepted.

[burleyman]

The 2960X's I have configured show this as the interface

interface GigabitEthernet1/0/5

Also the above was for a 3560 I think, or at least the host name was setup that way.

If he would post the output of show run for one of the interfaces we would be able to help.
