Nexus 3064PQ unable to configure management VLAN

[George Mason]

Hi,

I am facing a problem with a Nexus 3064PQ switch where I am trying to configure a management VLAN, which I can use to administer the switch. I am unable to use the management port on the back of the device as the incoming circuits to the rack are all over a trunked fibre port. I therefore need to configure a layer 3 VLAN interface and use that for remote management. I have assigned an IP to the VLAN interface and am able to ping that from the management network, however all attempts to SSH to the VLAN interface are refused.

The Cisco documentation suggests I should be able to configure a VLAN as a management SVI, which appears to be the right approach (mentioned here) however when I try to do this, the switch rejects the commands:

THW-NX1# conf t
Enter configuration commands, one per line. End with CNTL/Z.
THW-NX1(config)# feature interface-vlan
THW-NX1(config)# interface-vlan 103 management
% Invalid command at '^' marker.

As far as I can see, the device is of the correct version for the documentation to apply:

Software
BIOS: version 2.4.0
loader: version N/A
kickstart: version 5.0(3)U5(1f)
system: version 5.0(3)U5(1f)

I would be grateful of any assistance as I cannot see what I have missed or am doing wrong. There are no ACLs in place to block this traffic and I am able to ping the IP of VLAN 103's SVI.

I am able to configure the interface vlan on my box.

Hardware:-cisco Nexus 3064 Chassis ("48x10GE + 4x40G Supervisor")

software:- system: version 5.0(3)U3(2b)

N3K# show feature

interface-vlan 1 enabled

N3K(config)# interface vlan 103  >>>>>>> Can you use the following syntax?
N3K(config-if)# ip address 3.3.3.3 255.255.255.0
N3K(config-if)# no shut

N3K# show license usage

Hi,

Thanks for the response. I am able to add the IP address and configure the interface VLAN but am unable to configure that as a management VLAN, hence it won't accept SSH sessions etc.

http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/layer2/503_U3_1/b_Cisco_n3k_Layer_2_Switching_Config_503_U31/b_Cisco_n3k_Layer_2_Switching_Config_503_U31_chapter_00101.html#task_71991D8EFFB54DAB893C5E0855FF7AFD

Apparently I should be able to do the following:

switch# configure terminal
switch(config)# feature interface-vlan
switch(config)# interface vlan 5
switch(config-if)# management

However when I try, I get the following:

THW-NX1# conf t
Enter configuration commands, one per line. End with CNTL/Z.
THW-NX1(config)# show feature | i interface-vlan
interface-vlan 1 enabled
THW-NX1(config)# interface vlan 103
THW-NX1(config-if)# management

% Invalid command at '^' marker.

Hi,
I just happen to try on Nexus 3064T chasis and I was able to configure the same.
Only difference is the hardware and software.

software:- 6.0(2)U1(1a)

License:-
license usage
Feature Ins Lic Status Expiry Date Comments
Count
--------------------------------------------------------------------------------
LAN_BASE_SERVICES_PKG Yes - Unused Never -
ALGO_BOOST_SERVICES_PKG No - Unused -
LAN_ENTERPRISE_SERVICES_PKG No - Unused

config:
Nexus-3K(config)# feature interface-vlan
Nexus-3K(config)# interface vlan 5
Nexus-3K(config-if)# management
Nexus-3K(config-if)# >>> no error recieved.

Can you upgrade the firmware ?

Hi,

Just wanted to summarise what I did to fix this in the end, as I got it working today.

It appears that the software version I was running did not support the SVI management feature that I was attempting to use. I today upgraded to 6.0(2)U6(5c) and the management SVI worked correctly.

Thanks to all for the help
