Brocade VDX 6470 T - Can't remove Interface from Licenses


Good Morning Team,

My Issue:
  • I have 2x Brocade 6470T Switches stacked.
  • Each switch is licenses with 8x 10Gbe ports licensed
rbridge-id: 11
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
10G Port Upgrade license
Feature name:PORT_10G_UPGRADE
License is valid
Capacity: 8
  • I have two ports I am try to remove from from the assigned license.
#sh dpod
10G ports not assigned to a license:
11/0/46

Example of sh interface status of 11/0/46 for example

What is the switch firmware?
Hardware Rev : 137.4

What I have done:

Tried to release a port from a POD set using the following

Releasing a port from a POD set:

Once a port has been assigned to a Dynamic POD license port set, it remains licensed (or "reserved") untilthe userremoves the port from the port set.To remove a port from the port set,release the port with the dpod release command. Releasing a port removes it from the Dynamic POD license port set; the port appears as unassigned until it comes back online.

switch# configure terminal
Entering configuration mode terminal
switch(config)# interface 1/0/10
switch(conf-if-te-1/0/10)# shutdown
switch(conf-if-te-1/0/10)# exit
switch(config)# dpod 1/0/10 release
switch(config-dpod-1/0/10)# exit


Thank you for taking the time to read my question. Also, I hope you have a fantastic day.

Yes, this is as designed. As there is no license associated to this port, it will not come up, and any config will be removed after attempting to no shut the device.

When a port is connected, it should automatically assign a Dynamic license assignment (DPOD) unless there are no licenses available.

You will want to check the full output of your "show dpod" to see the total number of port assignments you have provisioned, how many are used and how many are available.

As your "show license" output shows a single 8port 10G upgrade installed, I will assume you have a total of 32 port assignments provisioned. (24 From the Base switch license + 8 Port Upgrade = 32 Total)

If your "show dpod" output lists:

code:
0 license reservations are still available for use by unassigned ports


Then you will will either need to remove a reservation off a port that is assigned a license and not in use, or install an additional 10G Port Upgrade.

If your system does show available licenses, however is not reserving the port, please try the following:

code:
VDX1# conf t
Entering configuration mode terminal
VDX1(config)# dpod 11/0/46
VDX1(config-dpod-11/0/46)# reserve
VDX1(config-dpod-11/0/46)# end


Then shut/no shut the port and verify if it comes up.

Ultimately if none of the above addresses your issue, I suggest you open a case with our TAC team and we can do some live troubleshooting with your to resolve your issue.

Good Morning,

If I understand you correctly, your goal is to remove this port (11/0/46) from using your installed 10G port license. From the output you have provided, the port is not associated to any license, so you have released it properly. There is a lot of information in "show dpod" here is an example from my lab:

Here you can see I have no 10G license installed, so therefore I only have use of 24x10G ports

VDX1# show dpod
rbridge-id: 1
48 10G ports are available in this switch
4 40G ports are available in this switch
No 10G Port Upgrade license is installed
No 40G Port Upgrade license is installed
Dynamic POD method is in use

24 10G port assignments are provisioned for use in this switch: -- Total number of ports available
24 10G port assignments are provisioned by the base switch license -- Base 24 ports included by default
6 10G ports are assigned to installed licenses: -- Total number of ports assigned to all licenses
6 10G ports are assigned to the base switch license -- Number of ports assigned to base (up to 24)
10G ports assigned to the base switch license:
1/0/1, 1/0/2, 1/0/3, 1/0/4, 1/0/5, 1/0/6
10G ports assigned to the 10G Port Upgrade license: -- No ports assigned as I have no upgrade installed
None
10G ports not assigned to a license: -- All other ports not in use or unlicensed
1/0/7, 1/0/8, 1/0/9, 1/0/10, 1/0/11, 1/0/12, 1/0/13, 1/0/14, 1/0/15, 1/0/16
1/0/17, 1/0/18, 1/0/19, 1/0/20, 1/0/21, 1/0/22, 1/0/23, 1/0/24, 1/0/25, 1/0/26
1/0/27, 1/0/28, 1/0/29, 1/0/30, 1/0/31, 1/0/32, 1/0/33, 1/0/34, 1/0/35, 1/0/36
1/0/37, 1/0/38, 1/0/39, 1/0/40, 1/0/41, 1/0/42, 1/0/43, 1/0/44, 1/0/45, 1/0/46
1/0/47, 1/0/48
18 license reservations are still available for use by unassigned ports

With the above information, and looking at the output you provided:

10G ports not assigned to a license:
11/0/46

This port is not assigned to any license. If you are trying to bring another port up, please check your entire "show dpod" output to confirm the number of ports you have assigned to all of your licenses as well as the number of licenses you have available for use.

I hope this answers your question and helps address your issue.

Is the real issue. shut / no shut is not working.

Thank you for getting back to me. If I don't want to use that port as a 10GB port, is it not possible to use it as a 1GBe port instead?

Unfortunately no, in order to use a port as 1G it needs to be also licensed as a 10G port.

Thank you Michael for your help. Your response time was amazing.

sw-psp-vcs-core01# show interface tengigabitethernet 11/0/46
TenGigabitEthernet 11/0/46 is up, line protocol is up (connected)

I found a port that was not being used and added it to the port that I needed and it came up!

One more question, Cisco switches have the write mem. Does that apply with the Brocades?
Userlevel 2
The most common deployment for VDX switches is in "Logcial Chassis" also referred to as "Distributed" mode. This allows the devices in a single fabric to save and sync their config in real time. There fore all changes are saved automatically and the commands "wr mem" and "copy run start" are disabled.

These commands are only used if you are in "Local Only" mode where the switch is acting as a stand alone device.

You can confirm the current mode by issuing the command "show vcs". Any version post 7.1 will be in Logical Chassis as the default.

Good Morning Mike,

I just wanted to follow up and thank you for such amazing support. The has been licensed, the interface is up,

I heard about how great the support is from this team, but to get this much color on an issue I faced for two days on this community page is greatly appreciated.
