BLADEOS 6.3 Application Guide

Known Issues

This section describes known issues for BLADEOS 6.3 on the 1/10Gb Uplink Ethernet Switch Module.

Software Upgrade Issues

￿Some time zones are different compared to release 6.1.2 and prior. After upgrading to release 6.3 or later, it is recommended that the administrator review the configured time zone and make any appropriate changes. (ID:29778)

￿The STG port priority value is different compared to release 5.x and prior. In release 5.x and prior, the priority value could be set to any integer from 0 to 255. In release 6.3 and later, the range is still 0 to 255, but must be specified in increments of 4 (such as 0, 4, 8, 12, and so on).

If the specified value is not evenly divisible by 4, the value will be automatically rounded down to the nearest valid increment whenever manually changing the priority value, when loading a configuration from prior to release 6.3, and during the software upgrade process. If using STG port priorities, after upgrading to release 6.3 or later, it is recommended that the administrator review the configured values and make any appropriate changes. (ID: 38556)

Access Control Lists

￿When an Access Control List (ACL) is installed on two different ports, only one statistics counter will be available. The GbESM does not support two different statistics counter for one ACL installed on two different ports.

￿The ACL filters for TCP/UDP work properly only on packets that do not have IP options.

￿When configuring an ACL to set 802.1p priority for in-profile packets, and updating the DSCP field using TOS bits for out-of-profile packets, the out-of-profile packets will have also the 802.1p priority set as defined in the in-profile setting.

￿Although the management port can be configured for port filtering option, actual port filtering will not occur, because the system filters out the management VLAN.

IGMP Relay

￿When having joins from multiple VLANs, and the multicast data transmitter is on a VLAN that did not receive any joins, multicast data is routed only if the flood option is disabled using the

/cfg/l3/igmp/adv/flood d command.

￿If an IGMP v2 joins an IGMP group on the same port where an IGMP v1 join has already been issued, the software will default to the IGMP v1 timeout value.
