---------------------- 8371 Release 1.1 PTF 1 ---------------------- PTF 1 is the first fix image for the 8371 Release 1.1 and is a replacement for the GA release and any engineering level code image that a customer may have installed. This PTF and Release 1.1 can be thought of as the active maintenance stream for 8371 Release 1. The Release 1.1 was a functional enhancement to Release 1.0. Please note that any Release 1.0 configuration can NOT be used for the Release 1.1, the configuration must be re-constructed from either default or null configuration. See the 8371 product support page for details regarding Release 1.1. APARs included: IR42911 - Problem with 2 port Bridge configuration, frames may not be Forwarded after bridge cache timeout occurs IR42927 - 8371 with dual ATM interfaces in use may not switch Lan Client Back on origional interface when interface is restored IR42929 - ATM interface hang condition when part of the ATM network Is disconnected, results in a few minute lock up condition Other fixes or changes: - Delete the improper logging of LEC.198 and LEC.102 messages in the ELS log of the 8371, these messages are informational and not errors and should not cause alarm. - Frame not copied counter improperly incremented, now set to 0. - File size for the Release 1.1 is 4095599 dated April 17, 2000 I. IP Filters on Bridge Interfaces If the configuration consists of bridge interfaces with an IP address configured using MSS / 8210 Release 2.2, and the design is to route IP traffic, then bridge filters should be defined to prevent the IP traffic from being bridged. Defining ethertype protocol filters for both IP and ARP on all of the bridge interfaces with IP address configured will insure that all IP traffic is routed reducing the traffic on those interfaces which will help reduce the transmit queue utilization. IMPORTANT: In all MSS / 8210 releases before Ver 2.2, IP traffic was by default filtered from the bridge and routed when an IP address was configured on a bridge interface. Therefore, if the an upgrade to Release 2.2 code is made from earlier versions, IP and ARP filters must be added to the bridge interfaces to configure the same function as the earlier versions. Below is the excerpt for the Release Notes for MSS / 8210 Release Ver 2.2 that references this situation: Bridging and Filtering IP on an Interface In some configurations of the MSS Server, an IP address was configured on a bridge port to block forwarding of IP traffic on that port. However, because MSS Server V2.2 supports bridging and routing of IP traffic on an interface, this configuration no longer filters IP traffic on the bridge port. IP packets destined to the MAC address of the bridge port are routed. All other IP packets are bridged. To block the forwarding of IP packets, you must configure a bridge filter. II. Variation in LEC Interface Aging Timers In configurations with several LEC interfaces defined with a large number of LE-ARP cache entries, staggering the aging timer of each LEC interface may help prevent the transmit queue from being filled with requests sent to refresh these entries from all LEC interfaces at one time. To change this time interval, the Aging Time value (C17) is changed from its default value of 300 in increments not less than 5. For example: If we have 5 LEC interfaces with larger LE-ARP caches, we may change the timers as follows: LEC #1 - 300 LEC #2 - 295 LEC #3 - 290 LEC #4 - 285 LEC #5 - 280 III. Broadcast Manager and Bridging Broadcast Manager Utilizing Broadcast Manager and Bridging Broadcast Manager as appropriate may help reduce broadcast traffic through the network.
