Command Rejected : Exceeded NNI ports Allowed

Dear Experts

,

I have some problem in cisco 3400ME switch.

There is only 4 ports allowed "port-type NNI" and then when i config more than four ports to NNI  i got Error msg

"Command Rejected : Exceeded NNI ports Allowed"

We are using c3400ME-12.2(44)SE.bin IOS

currently int fastethernet port 1 & 2 and GigabiteEther 1 & 2 are port-type NNI , when i give port 3 or any ports i got abeve mention error msg.

when i remove any one port from nni to uni and then config to any other port to NNI then we are able to config to NNI port.

So that means there are only 4 ports allowed to config on interface port-type NNI.

Which IOS upgrade to config all ports to NNI.

I need to config all ports are "switchport protected" and spanning-tree also on interface ( it is possible when all ports are in NNI tyne).

Pl help me.

Thanks in ADV,

Vaib...

Hello Vaib,

You can upgrade you device to 122-25.SEG3 (metro IP image)

and yes, it will support mere then 4 ports for NNI

Re: Command Rejected : Exceeded NNI ports Allowed

Hello Csawest.

According to the config guide starting 12.2(25) you can have more then 4 ports in NNI mode. So you need the change the mode

Configuring User Network and Network Node Interfaces

By default, all the 10/100 ports on the Cisco ME switch are configured as UNIs, and the SFP module ports are configured as NNIs.

You can use the port-type interface configuration command to change the port types. If the switch is running the metro base or metro access image, only four ports on the switch can be configured as NNIs at one time, but all ports on the switch can be configured as UNIs. Starting with Cisco IOS release 12.2(25)SEG, if the switch is running the metro IP access image, there is no limit to the number of NNIs configured on the switch.

When a port is changed from an NNI to a UNI, it inherits the configuration of the assigned VLAN, either in isolated or community mode. For more information about configuring UNI isolated and UNI community VLANs, see Chapter 11, "Configuring VLANs."

Beginning in privileged EXEC mode, follow these steps to configure the port type on an interface:

Command
Purpose

Step 1

configure terminal

Enter global configuration mode

Step 2

interface interface-id

Specify the interface to configure, and enter interface configuration mode.

Step 3

no shutdown

Enable the port, if necessary. By default, UNIs are disabled, and NNIs are enabled.

Step 4

port-type {uni | nni}

Change a port to a UNI or an NNI.

Step 5

end

Return to privileged EXEC mode.

Step 6

show interfaces interface-id

Verify the interface IEEE 802.3x flow control settings.

Step 7

copy running-config startup-config

(Optional) Save your entries in the configuration file.
