VDX port-profile-port & show vlan brief

Hi All,

Could you please help me understand the following.

In VDX, when there is a port(Te3/0/2 in this case) configured as a

port-profile-port and then a port-profile(test_pp_vlan_3100 in this case) is created,

the output of show vlan brief command shows that the vlan(3100) specified in

port-profile(test_pp_vlan_3100 in this case) is configured for port(Te3/0/2) even before

the port-profile is associated with a MAC. It seems this behavior is strange.

Following is the steps I followed in recreating this case.

EX:

(1) Te3/0/2 is configured as a port-profile-port.

sw0# show running-config interface TenGigabitEthernet 3/0/2

interface TenGigabitEthernet 3/0/2

fabric isl enable

fabric trunk enable

port-profile-port

no shutdown

!

(2) check the list of vlans and ports

sw0# show vlan brief

Total Number of VLANs configured : 20

VLAN       Name            State   Ports

(F)-FCoE                     (u)-Untagged, (t)-Tagged

                                  (c)-Converged

======== ================ ======= ================================================

1        default         ACTIVE  Te 3/0/2(c)

1501     VLAN1501        ACTIVE  Te 3/0/2(c)

(2) create a port-profile

sw0(config)# port-profile test_pp_vlan_3100

sw0(config-port-profile-test_pp_vlan_3100)# vlan-profile

sw0(config-vlan-profile)# switchport

sw0(config-vlan-profile)# switchport mode access

sw0(config-vlan-profile)# switchport access vlan 3100

(3) check the list of vlans again. It shows that vlan 3100 is configured for

     Te3/0/2 even before any association is done.

sw0# show vlan brief

Total Number of VLANs configured : 20

VLAN       Name            State   Ports

(F)-FCoE                     (u)-Untagged, (t)-Tagged

                                  (c)-Converged

======== ================ ======= ================================================

1        default         ACTIVE  Te 3/0/2(c)

1501     VLAN1501        ACTIVE  Te 3/0/2(c)

3100     VLAN3100        ACTIVE  Te 3/0/2(c)

(4) But when the port-profiles applied to interfaces are checked, the port profile

    with VLAN 3100 is not seen

sw0# show port-profile interface all

Interface        Port-Profile

Te 3/0/2         auto-test_vmotion

sw0# show port-profile name auto-test_vmotion

port-profile auto-test_vmotion

ppid 11

vlan-profile

  switchport

  switchport mode access

  switchport access vlan 1

What is this behavior? Is this a specification of NOS? or a bug?

I am using NOS2.1.1a.

Best Regards

Jagath
