Cisco 3850 LAN Base license slow throughput

Leave a comment

I was working on a installation and configuration of a C3850 switch with LAN base license.
What is in the name with LAN Base license…  As we all know from previous licenses (like 3750-X licenses), there is no routing available but… there is basic routing functionality available in the LAN base license for C3850 switches!
There are some limitations for routing with LAN base license though:

  • Maximum of 15 static routes
  • no routing protocols, only static routing

During the test phase of our implementation, we encountered performance issues:

  • File transfers inside VLAN’s: no issues
  • Inter-VLAN file transfers: slow throughput with a maximum of ~10Mb/s

Workaround: BUG in ASA IOS 8.4(4) and 8.4(5) adding network-object-nat

When upgrading from prior IOS 8.4 to 8.4(4) and 8.4(5), the configuration will be converted for the new IOS without any problems. But when you’re creating a new Network Object NAT rule, you’ll get a nasty error:

ERROR: NAT Policy is not downloaded

There’s no solution for this error at this point (january 2013), Cisco TAC mentioned me that the development team is still working on this issue but it’s hard for them to reproduce this error in their lab.
But.. there is a workaround available!
