Nexus port-security

[Bob K]

Does anyone know if the Nexus 3548's are capable of the port-security feature? I'm getting a "not supported on this platform" message. Is this a limit of the hardware or IOS? We're running n3500-uk9.6.0.2.A8.7b.bin. If this is a IOS issue does anyone know which release supports port-security?

Hi
haven't done this but says in docs its there 7.x release but has to be global

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/security/7x/b_Cisco_n3k_Security_Config_7x/b_Cisco_n3k_Security_Config_7x_chapter_01101.html#con_1210993

Prerequisites for Port Security

Port security has the following prerequisites:
You must globally enable port security for the device that you want to protect with port security.

I know it's a global command using the feature command to enable it but that doesn't work. enabling the feature I get an error.
(config)# feature port-security
Port-security is not supported on this platform

I don't think switching from n3500-uk9.6.0.2.A8.7b.bin to 6.0(2)A8(11) will help. There is a 7.0(3)I7(6) available but the description is "Cisco Nexus 9000/3000 Standalone Switch" and I don't think that will work in our environment. Port-security is a common config, so it seems strange that I can't enable it on this model with this image and as I see there are no licensing requirements for this feature either?

[Mark Malone]

theres no license requirements but that doc where its enabled globally is using version 7 , the release notes for your version will be online too , it may have only been released in later versions

Thanks Mark, I opened a case with Cisco to get a definitive answer. I'm being to believe it is IOS related. I'll post what Cisco says is anyone else has this issue. 

Thanks Bob.

You need to enable  ( by default it was disabled)

to check enable or disable

config t

(config)# show port-security ( you will not see this command that means feature not enabled.

(config)# feature port-security

(config)# show port-security

[Bob K]

(config)# feature port-security
Port-security is not supported on this platform
(config)# sh port-security
^
% Invalid command at '^' marker.

strange : can you please show us show version

back i believe tested with 7.X

I dont see it any release notes for 3548 models , its in the 3k general series but 7 has it supported as per the link

[Bob K]

Seems the 3548 doesn't support the port-security feature. 

This is Cisco's response:

Unfortunately, there are no current plans to support port-security on Nexus 3548.

There are some commands available in the software, but as you have found, they do not work. This is why there is no configuration guide for port-security on N3K.

[Mark Malone]

They should state that then in the general release docs for the 3000 series as its under that release but thanks for posting back the answer
