S7706 – Issue when trying to remove 2 unused interfaces which are included in a CSS port.

Publication Date:  2017-10-19 Views:  497 Downloads:  0
Issue Description

Fault symptom: The customer had a CSS with these interface configured:

 

[CSS_MASTER] display css css-port

Logic Port          Num  Phy Port                      Status

 css-port2/1      4    XGigabitEthernet2/1/0/0       up

                              XGigabitEthernet2/1/0/1       up

 

The CSS was configured with these interfaces:  

 

[R00_MASTER]display css css-port

Logic Port          Num  Phy Port                      Status

 css-port2/1      4    XGigabitEthernet2/1/0/0       up

                             XGigabitEthernet2/1/0/1       up

                             XGigabitEthernet2/1/0/2       down

                             XGigabitEthernet2/1/0/3       down

(B)css-port2/2      2    XGigabitEthernet2/3/0/0       up

                               XGigabitEthernet2/3/0/1       up

 

During their first setup of CSS they did a mistake and configured the below interfaces but they would want to remove them from CSS since they didn’t use them:

 

XGigabitEthernet2/1/0/2      

XGigabitEthernet2/1/0/3      

 

Version information: Quidway S7706,ES0B07706, V200R007C00SPC500

 

Solution

After checking the documentation I found that in order to restore a physical member port as a service interface, run the shutdown interface command in the CSS port view and then run the undo port interface enable command.

But the customer couldn’t applied the undo port interface enable. Those were the commands applied :
The command that he entered were:

[R00_MASTER]dis css css-port

Logic Port          Num  Phy Port                      Status

   css-port2/1      4    XGigabitEthernet2/1/0/0       up

                       XGigabitEthernet2/1/0/1       up

                       XGigabitEthernet2/1/0/2       down

                       XGigabitEthernet2/1/0/3       down

(B)css-port2/2      2    XGigabitEthernet2/3/0/0       up

                       XGigabitEthernet2/3/0/1       up


He tried for both interfaces of CSS-Port2/1 the sequence of commands that I advised :

 

[R00_MASTER]interface css-port  css-port2/1

[R00_MASTER-css-port2/1]shutdown interface XGigabitEthernet2/1/0/2

Info: This operation may take a few seconds. Please wait for a moment....succeeded.

[R00_MASTER-css-port2/1]shutdown interface XGigabitEthernet2/1/0/3

Info: This operation may take a few seconds. Please wait for a moment....succeeded.

 

These were succesfuly shutdowned:

 

<R00_MASTER>dis css css-port

B : broadcast   *down : administratively down

Logic Port          Num  Phy Port                      Status

   css-port2/1      4    XGigabitEthernet2/1/0/0       up

                       XGigabitEthernet2/1/0/1       up

                       XGigabitEthernet2/1/0/2       *down

                       XGigabitEthernet2/1/0/3       *down

(B)css-port2/2      2    XGigabitEthernet2/3/0/0       up

                       XGigabitEthernet2/3/0/1       up

 

 

But when he tried to run the second command undo port interface enable there was an error :

[R00_MASTER-css-port2/1] undo port interface XGigabitEthernet2/1/0/2 enable

Error: Interface XGigabitEthernet2/1/0/0 XGigabitEthernet2/1/0/1 XGigabitEthernet2/1/0/2 XGigabitEthernet2/1/0/3 should be operated at the same time.

 

After checking the diagnostic I noticed that for slot 1 he was using an ES1D2X16SFC0 LPU. As I checked in the precautions, a group of four ports must be configured as CSS physical member ports together:

Given this, the customer connected a passive cable to those ports since he cannot use them for other purposes.
