HP 12500 Switch Series - 12500-CMW710-R7129 Release Notes

6
Restrictions and cautions
Restriction 1
[Configuration management] Do not perform any configuration within one minute before an
active/standby switchover because the configurations might be lost after the switchover.
Restriction 2
[Tunnel] IPv6 addresses that begin with 2002 can only be used on 6to4 tunnels. Use of such
addresses on other types of tunnels causes forwarding problems.
Restriction 3
[QoS] Make sure the CBS and EBS configured for CAR are larger than the maximum packet size.
Otherwise, the CAR policy cannot regular traffic precisely.
Restriction 4
[Port] Do not insert an optical-to-electrical conversion module within 1 second after it is removed.
Otherwise, the ports on the module cannot go up.
Restriction 5
[Port] Replace failed fiber modules as soon as possible to avoid continual failure event alarms.
Restriction 6
[QoS] If the weights configured for two WRR queues have a big difference, the WRR queue with
higher weight might get bandwidth lower than it should have been assigned. If the ratio is not in its
simplest form, the software automatically reduces the WRR queue ratio to its simplest form to
avoid the problem. For example, if the configured WRR queue weight ratio is 20:30, the effective
ratio will be 2:3.
Restriction 7
[Port] After you configure Jumbo frame forwarding or change the port mode between LAN and
WAN on a 10-GE port that uses a single-mode optical fiber, you must remove and then insert the
fiber. Otherwise, the LED of the port turns on improperly.
Restriction 8
[L3VPN] If system-working-mode standard is configured, the reserved VLANs for MPLS L3VPNs
cannot be used for any other services, including Layer-2/-3 forwarding.
Restriction 9
[MAC] Each time the number of MAC address entries on a port or VLAN reaches the
user-configured limit, the system displays a warning message. If this message is continually
displayed for a VLAN or port, check the port or VLAN for MAC attacks and shut down the affected
port or ports as necessary.
Restriction 10
[Console] Flow control settings are not configurable for console logins.
Restriction 11
[IRF] After being bound to an IRF port, an Ethernet port supports only the shutdown, description,
and display commands.
