[c-nsp] nexus 5010 error %STP-2-VLAN_PORT_LIMIT_EXCEEDED:

[Tóth András]

Hi Arne,

The error message itself is pretty self-explanatory, you are having
too many active STP instances (vlans) on ethernet interfaces. Try
pruning the vlans by modifying the allowed vlan list on your trunk
ports and remove unnecessary vlans.

You can see the limitations for 4.1(3) release here:
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration_limits/limits_413/Cisco_Nexus_5000_Series_Configuration_Limits_for_Cisco_NX_OS_Release_413_chapter1.html


Release 4.1(3) is pretty old and you can increase the scalability and
configuration limits by upgrading to a newer release such as 5.0(3) or
5.1(3). I've included the configuration limits for these versions
below:
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration_limits/limits_503/nexus_5000_config_limits_503_n2_1.html

http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration_limits/limits_513/nexus_5000_config_limits_513.html


Upgrading from 4.1(3) to 5.1(3) will be disruptive, unless you go
through some interim versions. More information is in the Release
Notes in the "Supported Upgrade and Downgrade Paths" section.

Best regards,
Andras
