I have been having complaints of a "slow connection" from several new remote sites.
The sites are connected via an MPLS L3VPN service into Cisco 2921's, and we are using Cisco GET-VPN to encrypt the traffic between our locations. All locations have either 100Mbps or 1Gbps circuits, so speed should not be an issue.
However, upon conducting iperf tests from one location to a known working location, I found that my bandwidth tops out around 85Mbps.
Further investigation on the 2921's gives many occurrences of the following error message in the logs:
006555: Jan 3 08:19:09.573 EST: %CERM-4-TX_BW_LIMIT: Maximum Tx Bandwidth limit of 85000 Kbps reached for Crypto functionality with securityk9 technology package license. 006556: Jan 3 11:21:37.069 EST: %CERM-4-RX_BW_LIMIT: Maximum Rx Bandwidth limit of 85000 Kbps reached for Crypto functionality with securityk9 technology package license.
I have verified that our older locations using 2821's do not have this issue... is this something to do with IOS 15, the ISR Gen2's or both?
