bulk config change job

I'm trying to find a way to search every switch config for a specifc VLAN setting. When that VLAN is found, remove spanning-tree portfast from those ports.

The goal of this being to create a scheduled job which will run out and do this. Either by searching the latest downloaded running configs, making the changes and then uploading them all back to each switch or by making the change on each switch directly.

thanks!

What is the specific VLAN setting you are looking for? Is it already something gathered in NCM inventory reports?

Spanning-tree portfast.

I need to scan all our switches (or downloaded configs) and apply a no spanning-tree portfast for switchports in a specified VLAN. The script, in plain english would do this:

Scan all configs for ports using VLAN 301

For every port discovered in this VLAN, set the port to no spanning-tree portfast

I can scan all our configs and find instances of VLAN 301 but cannot apply the setting with search/replace. Here is an example before and after using it:

Before-

interface fastethernet 0/1

switchport access vlan 301

spanning-tree portfast

replace "switchport access vlan 301" with "switchport access vlan 301 \r no spanning-tree portfast"

Result-

interface fastethernet 0/1 \r no spanning-tree portfast

switchport access vlan 301

spanning-tree portfast

So it will apply the setting then immediately remove it on the third line.

thanks
