Cisco 3850X - ACL turns up without configuring ?

Sheikh Islam
Level 1
Level 1

Hello Everyone,

I have just recently configured a new 3850X.

We had 3750Xs on our network. An Infrastructure refresh is now planned and we got 3850Xs to replace the 3750Xs.

 

I started configuring one of the switch and pasted all standard config that we used to have on our 3750Xs. Added some extra bits that I thought may be necessary. Here is the config I used -

Any ideas why ? 

Do I need these ACLS ?

If not, what do you suggest we do ?

Also, Any other advise regarding this config will be highly appreciated.

 

Best regards,

Sheikh

Hi,

All ACLs are normal behavior of new software and will automatically be added in configuration. Don't worry about it and if you need to reconfigure then you can also change.

 

These all are IOS and startup configuration files and yes you need for all files. Currently, this is upload with "Installed mode".

Hi,

All these extra ACL and policies are normal and are part of the new software and new platforms. Also, you can't delete or modify them.

So, no need to do anything with them.

HTH

Thanks.

 

Do I need all of these file sin the Flash:

Hi,

All ACLs are normal behavior of new software and will automatically be added in configuration. Don't worry about it and if you need to reconfigure then you can also change.

 

These all are IOS and startup configuration files and yes you need for all files. Currently, this is upload with "Installed mode".

Hi


Are you running traces on your switch. You can check with "show platform software trace message" - see below ref

 

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/16-3/command_reference/b_163_consolidated_3850_cr/b_163_consolidated_3850_cr_chapter_010100.html

 

You could maybe running into the bug CSCvc14038 although your software isn't listed as an affected release.

 

To clean up unused software packages in flash see below link:
