Layer 2 IP Trunk Hash configuration Trunk hash parameters are set globally for the GbE2c Ethernet Blade switch. You can enable one or two parameters, to configure any of the following valid combinations: • SMAC (source MAC only) • DMAC (destination MAC only) • SIP (source IP only) • DIP (destination IP only) • SIP + DIP (source IP and destination IP) • SMAC + DMAC (source MAC and destination MAC) The following table describes the IP Trunk Hash Configuration commands. Table 113 IP Trunk Hash Set commands Command Description portchannel hash source-macaddress Enable or disable trunk hashing on the source MAC. Command mode: Global configuration portchannel hash destinationmac-address Enable or disable trunk hashing on the destination MAC. Command mode: Global configuration portchannel hash source-ipaddress Enable or disable trunk hashing on the source IP. Command mode: Global configuration portchannel hash destination-ip- Enable or disable trunk hashing on the destination IP. address Command mode: Global configuration portchannel hash sourcedestination-ip Enable trunk hashing on the source and destination IP. Command mode: Global configuration portchannel hash sourcedestination-mac Enable trunk hashing on the source and destination MAC address. Command mode: Global configuration show portchannel hash Display current trunk hash configuration. Command mode: All Link Aggregation Control Protocol configuration The following table describes the LACP Configuration commands. Table 114 LACP Configuration commands Command Description lacp system-priority {} Defines the priority value (1 through 65535) for the switch. Lower numbers provide higher priority. The default value is 32768. Command mode: Global configuration lacp timeout {short|long} Defines the timeout period before invalidating LACP data from a remote partner. Choose short (3 seconds) or long (90 seconds). The default value is long. Command mode: Global configuration NOTE: HP recommends that you use a timeout value of long, to reduce LACPDU processing. If your switch's CPU utilization rate remains at 100% for periods of 90 seconds or more, consider using static trunks instead of LACP. show lacp Display current LACP configuration.

Configuration Commands 108
Layer 2 IP Trunk Hash configuration
Trunk hash parameters are set globally for the GbE2c Ethernet Blade switch. You can enable one or two parameters,
to configure any of the following valid combinations:
•
SMAC (source MAC only)
•
DMAC (destination MAC only)
•
SIP (source IP only)
•
DIP (destination IP only)
•
SIP + DIP (source IP and destination IP)
•
SMAC + DMAC (source MAC and destination MAC)
The following table describes the IP Trunk Hash Configuration commands.

The following table describes the LACP Configuration commands.
Table 114
LACP Configuration commands
Command
Description
lacp system-priority {<
1-65535
>}
Defines the priority value (1 through 65535) for the switch. Lower
numbers provide higher priority. The default value is 32768.
Command mode
: Global configuration
lacp timeout {short|long}
Defines the timeout period before invalidating LACP data from a remote
partner. Choose
short

.
Command mode
: Global configuration
NOTE:
HP recommends that you use a timeout value of
long
, to reduce LACPDU processing. If your switch’s CPU
utilization rate remains at 100% for periods of 90 seconds or more, consider using static trunks instead of LACP.
