Port Security on CISCO Nexus 9000 Switch

Hey Fellas,

I need some help on configuring port security on my CISCO Nexus 9000 switch. Actually I'm unable to configure port security in the switch because commands are not identifying. I tried below commands which are given in Cisco Nexus 9000 Series NX-OS Security Configuration Guide, Release 7.x.

switch# configure terminal
switch(config)# feature port-security

switch(config)# interface ethernet 2/1
switch(config-if)# switchport port-security

But unfortunately both these command sets are not identifying by my switch. (Refer attached images.) What could be the issue with this?

Hello @IshanWickramarachchi,

What is the Firmware version?

nxos.7.0.3.I4.6 ? Port-security was introduced in NX-OS 7.0(3)I5(1) and later...

Thanks.

Hey,

Thanks for the reply. Below are the version details of my switch.

BIOS: version 07.56
NXOS: version 7.0(3)I4(8b)

As per your update, i think issue is with my firmware. I'll check and work on this.

Thanks & Best Regards.
