OmniSwitch 6600/7000/8800—Release 5.1.6.R02 page 107
PR 65197
The qos default queues command may cause the NI to have a different configuration than the CMM.
Workaround: The qos default queues <num> command requires a reset of the NI before it takes effect.
One can reset the NI by executing the no power ni <num> command, and then the power ni <num>
command. One can also execute the reload working no roll-back for the setting to take effect.

Using Xircom CreditCard Ethernet 10/100 + Modem 56, if the speed and duplex of both the OS7-ENI-
C24 switch and the NIC are fixed to 100FD, then no link is detected.
If auto-negotiation is enabled on the switch, the connection is only detected as 100HD even though the
NIC is configured to 100FD.
Workaround: By using auto-negotiation, a link can be detected, although this will only be 100HD and
not 100FD.

Without a common denominator, a link does not come up when one, or both sides turns on autonegotia-
tion. For example, when autonegotiation is turned on, on a port on a switch, the link stays down if the link
partner has:
• Autonegotiation is turned off and the local port is enforced to FULL duplex; or,
• Autonegotiation is turned on, but the speed mismatches other than auto; or,
• Autonegotiation is turned on, but the duplex mismatches other than auto.
Workaround: This follows IEEE 802.3 recommendations. Both sides should have a common denomina-
tor. Either the switch side or remote side should change the configuration.
