Operating Notes and Troubleshooting

J4881B and J4889B Modules
The new "B" models of the ProCurve 9300 EP 48-port 10/100-TX modules (J4881B and J4889B) have the following
boot code and software requirements:
•
Boot code version 07.06.05 (or later) is required.
•
Software version 07.8.00a (or later) is required.
Also, the J4881B and J4889B have the following restriction:
Condition. Half-duplex operation is not supported on the "B" models
Solution. Insert an autonegotiating 10/100 switch between the 9300 port and the connected device. The link between
the 9300 port and the switch will autonegotiate to 100 Mbps full-duplex, and the link between the switch and the
connected device will come up at half-duplex.
Redundant Management Module Operation
When two redundant management modules are installed in a Series 9300 routing switch, the two modules work
together as active and standby management modules. If the active module becomes unavailable, the standby module
automatically takes over system operation. If this occurs, the routing tables, ARP tables, etc. are all updated
dynamically, as if the routing switch had been rebooted. As a result of this reconvergence, a noticeable, temporary
network disruption occurs. The duration of the disruption depends on the number of routes being utilized through
the device, and can be significant.
Auto-Negotiation Between the ProCurve 9300M Routing Switches and Extreme Summit Switches
Condition. Auto-Negotiation between ProCurve 9300M routing switches and Extreme Summit switches may some-
times fail.
Solution. Disable auto-gig on the routing switch port(s) attached to the Extreme Summit switch.
For example, use the following CLI commands to disable auto-gig on port 2 in slot 1 of the 9304M Routing Switch:
ProCurve 9304M (config)# int e 1/2
ProCurve 9304M (config-if-1/2)# no auto-gig
Web Management Interface Running Slow or Failing To Respond
Condition. The web management interface on the routing switch times out or does not respond. This can occur when
the routing switch CPU is processing an excessive amount of broadcast traffic.
Solution. The Web management interface recovers automatically when the CPU is sufficiently free of broadcast
traffic. Because the web management interface is a low priority for the CPU, you may want to take steps to reduce
the broadcast traffic on your network. One method for doing this is to use a network management tool to determine
the "top talkers" on your network, then create VLANs to segment the network for optimum traffic control.
Web Management Interface "Not Available" or "In Use"
Condition. You are unable to access the web managment interface.
Solution. A routing switch allows only one session of the web management interface at any given time. Thus, if one
user is accessing the routing switch via the web, the not available or in use messages will appear to another user who
is trying to access that routing switch through the web management interface.
