Hi Mark,

Hi There,

Can anyone tell me how to make default port in Cisco Data Center 5K Switch?

When I do show run int e2/10 [the output shows as follows]

switch(config-if)#

medium p2p

This interface has been changed into L3, I have tried to bring it back into default [L2] mode but it never comes back in default mode.

I used to convert a Layer 3 interface back into a Layer 2 interface, by using switchport command.

Found this doc but doesn't work

MDS Configuration

Same question for the MDS? how do we make default port in MDS ??

Thank you for your reply.

Hi

To return to out of the box use the below in conft mode

NX-OS

LAB5KA1(config)# default interface ethernet 2/10

Thanks mate,

i will try and get back to you, also do you know how I can access 5k switch on cisco learning site?

Thx again.

Sorry not familiar with that site , yes let us know how it goes should work fine im always defaulting ports it will wipe it completely

Hi Mark,

any idea with MDS? I tried but it doesn't wipe config of interface.

Mark Malone · ‎05-24-2016

Sorry I don't have an MDS to test on maybe someone else can answer that part that's more familiar with the product , looking at one of the MDS 9000 cli docs you can though turn it straight to a trunk switchport that should take it back to layer 2 if it works for you

Configuring Trunk Mode

To configure trunk mode, follow these steps:

	Command	Purpose
Step 1	switch# config t	Enters configuration mode.
Step 2	switch(config)# interface fc1/1 switch(config-if)#	Configures the specified interface.
Step 3	switch(config-if)# switchport trunk mode on	Enables (default) the trunk mode for the specified interface.
	switch(config-if)# switchport trunk mode off	Disables the trunk mode for the specified interface.
	switch(config-if)# switchport trunk mode auto	Configures the trunk mode to auto mode, which provides automatic sensing for the interface.

hi Mark,

this command didn't work, and it's for 7K- Switch

LAB5KA1(config)# default interface ethernet 2/10 OR int fc1/1

Mark Malone · ‎05-26-2016

Hi

That's a 5K switch I took it off as an example , its for nx-os and ios and ios-xe not just 7ks it should work what do you get after dfault in conf t

kickstart image file is: bootflash:///n5000-uk9-kickstart.7.0.6.N1.1.bin
system image file is: bootflash:///n5000-uk9.7.0.6.N1.1.bin
LAB5KA1# conf t
Enter configuration commands, one per line. End with CNTL/Z.
xir-d126sas02(config)# default ?
interface Interface configuration

LAB5KA1(config)# default interface ?
bdi           Bdi interface
ethernet      Ethernet IEEE 802.3z
loopback      Loopback interface
mgmt          Management interface
port-channel Port Channel interface
vlan          Vlan interface

xir-d126sas02(config)# default interface

Hi Mark I found this solution.

Can you try at your end and confirm if it works, I dn't have any empty port to test in my production switch.

Usage Guidelines

When the system default switchport shutdown command is issued, any switchports (including FEX HIFs) that are not configured with no shutdown command are shut down. To avoid the shutdown, configure the switchports with no shutdown command.

Examples

This example shows how to set all ports as Layer 3 routed ports:

switch# configure terminal

switch(config)# system default switchport shutdown

switch(config)#

This example shows how to reset all ports back to Layer 2 switchports:
