LACP/LAGG hashing on layer 4 (UDP/TCP-port) possible?
Posted: 27 Mar 2015 03:39
Hi,
is the 6450 able to perform LACP/LAGG hashing on layer 4 (UDP/TCP-port)? If yes how do I activate that?
The only setting I've found so far that has something to do with hashing:
And what "XOR" and "CRC" actually means isn't documented excactly:
Thanks and regards,
Nils

The only setting I've found so far that has something to do with hashing:
Code: Select all
hash-control mode fdb ?
^
XOR CRC
(CMM Chassis Supervision Command Set)
And what "XOR" and "CRC" actually means isn't documented excactly:
Code: Select all
hash-control mode fdb
Configures the hash control method on the switch. Depending on this configuration, hashing algorithm
used by various applications for Layer 2 table lookup is affected.
hash-control mode fdb { xor | crc }
Syntax Definitions
xor
Sets hash control lookup to XOR mode.
crc
Sets hashing to extended mode.
[...]
Usage Guidelines
• The hash control setting impacts the fabric load balancing for chassis based products.
• Changing the hash control mode affects the hashing algorithm for Link Aggregation and EMCP.
• Changing the hash mode requires a switch or stack reboot.
