HP 12500 Switch Series - 12500-CMW710-R7128 Release Notes

Restriction 11

[IRF] After being bound to an IRF port, an Ethernet port supports only the shutdown, description, and

display commands.

Restriction 12

[IRF] The BFD MAD VLAN must not have physical loops or be configured for any services other than BFD

MAD.

Restriction 13

[Enhanced IRF] In enhanced IRF mode, the following requirements must be met:

 Each IRF member switch must have two MPUs.

 The IRF fabric uses a ring topology.

 The downstream switch must have one link to each IRF member switch and aggregate these links in

an aggregation group.

Restriction 14

[IRF] The physical ports bound to IRF-port 1 (west port) on a switch must be connected to the physical

ports bound to IRF port 2 (east port) on its neighbor switch. If IRF-port 1 on one switch is connected to

IRF-port 1 on the other, and the physical ports have been UP, system exceptions will occur. To recover the

system, you must connect the physical ports correctly and reboot all the member switches.

Restriction 15

[Enhanced IRF] In enhanced IRF mode, all ports in chassis do not support routed mode or RRPP.

Restriction 16

[IRF] If a 1XXX release switch attempts to join a 7XXX release IRF fabric, the software auto-update

function cannot automatically synchronize the 7XXX release software to the joining switch. Likewise, if a

7XXX release switch attempts to join a 1XXX release IRF fabric, the software auto-update function cannot

automatically synchronize the 1XXX release software to the joining switch.

Restriction 17

[EVI] To avoid loops, do not assign transport-facing ports to extended VLANs. To avoid data breach,

make sure all edge devices in an EVI network maintain the same list of extended VLANs.

Restriction 18

[Active/standby switchover] An active/standby switchover can be started only if the HA actions for the

most recent active/standby switchover have been complete in all MDCs. Before an active/standby

switchover is complete, interface card and MDC manipulations are not allowed. Examples include

interface card removal or insertion, card assignment or removal for MDCs, and port assignment or

removal for MDCs.

Restriction 19

[Device management] Long-period of Type-B (for example, LST1SF08B1 and LST1SF18B1) and Type-C

(for example, LST2SF08C1 and LST2SF18C1) switching fabric module mixture is not allowed, but

short-period of mixture is allowed to prevent traffic interruption during a hardware upgrade.

Open problems and workarounds

None.
