50 Known limitations and considerations in this release

the broadcast to 10. If the rate limit value is changed to 500 on the disabled

port of the MLT, the rate limit value of the active port changes to 500, but this

port still limits the broadcasts to 10 rather than allowing 500. This behavior

continues even if the disabled port is later enabled. (Q00805123)

• While copying a large file from the PCMCIA to flash, the SMLT/LACP ports

may transition. (Q00906148)

RSMLT

• If you are using RSMLT instead of VRRP, you need to configure the RSMLT

holdup-timer to 9999 in order to provide indefinite peer backup. (Q00789564)

• When peer switches configured to use RSMLT do not have the same DHCP

configuration, unexpected results can occur. If there is a discrepancy in the

DHCP configuration, RSMLT reroutes the traffic. If the DHCP lease expires

while traffic is being rerouted and DHCP is not properly configured on both

core switches, then users could lose the connectivity. (Q00787428)

• IPX RSMLT failover time may be greater than 30 seconds. This is due to the

RIP/SAP learning process. (Q00745690)

IPX

• Occasionally, a client cannot establish a session with the server. The problem

may be a network latency issue with the Windows XP NetWare client version

4.90.0.0 for Windows XP. The problem is caused by setting the Auto_Frame

detection parameter, which is found under the NwLink settings. Nortel

Networks recommends not using this parameter. (Q00812779)

• Using Device Manager, the IPX encapsulation type of an interface cannot be

changed, whereas the CLI allows you to do so using the following CLI

command:

config vlan <vid> ipx encapsulation <IPX-network-number>

(Q00910444)

• Because of some Device Manager inconsistencies, Nortel Networks highly

recommends that you enter the CLI command, after enabling RSMLT using

Device Manager:

config vlan <

vid> ipx rsmlt enable
