Restrictions and cautions
1. SFP+ Direct Attach Cables are not recommended for use as IRF connections because failover and
recovery times are extended when this form of copper connection is use. Optical IRF connections
are recommended to optimize IRF failure, recovery and convergence times.
2. It takes more than half an hour to collect diagnostic information when the IRF has many
configuration parameters.
3. The hp 7500 product family supports four IRF members in R6635. There are several setup and
configuration limitation, please check the Command Line Manual and Operation Manual of new
release for detail.
4. If you enable multicast ARP and connect the device to an NLB server through an aggregate
interface, any port that receives client traffic must not reside on the same card as any member p ort
of the aggregate interface.
Open problems and workarounds
LSD68672
 Symptom: The IRF fabric may split.
 Condition: Reboot an IRF fabric comprised of four switches. If the switches are not synchronously
rebooted.
 Workaround: Make sure the switches have similar card configurations, can back up each other,
and are rebooted at the same time. If the IRF fabric splits, reboot the smallest IRF system so the
switches can join the system to re-form a 4-chassis fabric.
LSD62272
 Symptom: RRPP fails to operate.
 Condition: If the RRPP control VLAN ID is identical with the subinterface VLAN ID.
 Workaround: Do not configure the same VLAN ID for them.
