CiscoACE to F5 Big IP LTM migration
Hi, I'm upgrading from Cisco ACE to BigIP LTM. My Cisco devices are in bridge mode, so I have to keep that config for LTM. With the BigIP LTM I have done all my tests using a separate partition (other than Common). In this partition I have a VLAN group with two members (external and internal) and bridging enabled. External and Internal interfaces are not tagged. Everything works as expected. Since I have few contexts in the Cisco ACE I have to create Partitions and RDs to match with the number of contexts. I have tagged the interfaces based on the tagging I already have on the network, and create a VLAN group for each Partition. The switch ports where LTM interfaces are connected are set for trunk mode (Cisco) with dot1q encapsulation since they have to support multiple VLAN. When I do this it creates a loop and STP blocks one the ports (either the one corresponding to the external or internal interface of the LTM). I've been looking through the manuals, and as well on questions on dev central but I did not find anything similar. Did anybody encountered this issue or if you know of any document, white-paper, Q and A that cover this scenario? Any input is greatly appreciated. Thanks
BIP-IP 1600 VLAN bridge performance degradation
Hello, I have a BIP-IP 1600 series setup as part of my thesis work. The setup is as follows: (VLAN=20) Client1 --- F5 --- Server1 (VLAN=10) 572 Mbit/s. Client1 --- Cisco --- Server1 (No VLAN) 937 Mbit/s In the setup I have two VLANs, one public and one private. I do bridge'ing between the VLANs in the BIG-IP, but for some reason that downgrades the performance. In the bridge'ed setup with two machines directly connected to the BIG-IP on two separated VLANs the reported speed is around 572 Mbit/s. For a normal link the iperf reported speed is 937 Mbit/s when the traffic is only directed through a cisco switch. Is this normal behavior for the BIP-IP to degrade the performance, or I am doing something wrong? Thanks!
