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

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 disruption during a hardware upgrade.

Restriction 20

[MDC with IRF] If an MDC on a two-chassis IRF fabric contains only interface modules on the

subordinate chassis, BFD cannot work in the MDC.
