28 Release Notes for Catalyst 6000 Family Software Release 5.x
Open and Resolved Caveats in Software Release 5.2(2)CSX
• If protocol filtering is configured for an EtherChannel before the channel forms, it works
correctly. If you configure protocol filtering after the channel has formed, it may not work
correctly for transmitted traffic. This problem is fixed in software release 5.2(2)CSX.
(CSCdm16439)
• On switches with more than 100 VLANs, after removing a module or entering a set module
power down command, wait at least 60 seconds before putting the module back into service,
either by reinserting it or by entering a set module power up command. This problem is fixed
in software release 5.2(2)CSX. (CSCdm19125)
• The supervisor engine software incorrectly allows configuration of the MSM as a SPAN
destination port. When configured as a SPAN destination port, the MSM ignores the SPAN
traffic. If you configure an MSM as a SPAN destination port, remove it from the destination port
list with the set span disable mod_num/port_num command. This problem is fixed in software
release 5.2(2)CSX. (CSCdm20714)
• When the SPAN destination port is a trunk port, the encapsulation matches the trunk type: ISL
or 802.1Q. When the SPAN destination port is an access port, the default encapsulation is
802.1Q. The default encapsulation cannot be changed on Gigabit Ethernet access ports used as a
SPAN destination. To disable 802.1Q encapsulation on other ports, enter a set trunk
mod_num/port_num off command before entering a set span command. This problem is fixed in
software release 5.2(2)CSX. (CSCdm20968)
• When VTP Pruning is enabled, some VLANs that show as Pruned by VTP Pruning might be
treated as joined by GVRP so that GVRP declares those VLANs on all of the GVRP-enabled
trunks. This problem is fixed in software release 5.2(2)CSX. (CSCdm21455)
• The WS-X6248-TEL module spanning tree state shows forwarding but is not able to switch any
traffic. This problem is fixed in software release 5.2(2)CSX. (CSCdm21520)
• On EtherChannels between 10/100 Ethernet switching modules, occasionally after changing the
speed of the EtherChannel ports from 10 Mbps to 100 Mbps or 100 Mbps to 10 Mbps, the
channel may form with fewer ports or multiple channels may form. To restore the original
EtherChannel configuration, disable all the ports in the EtherChannel and then enable them. This
problem is fixed in software release 5.2(2)CSX. (CSCdm22352)
• With redundant supervisor engines, after switch over to the standby supervisor engine, SNMP
applications on network management systems fail when accessing cdpCacheTable
(1.3.6.1.4.1.9.9.23.1.2.1). This problem is fixed in software release 5.2(2)CSX. (CSCdm22434)
• The showconfig command does not have the SPAN create option if multiple SPAN sessions have
been created. If a configuration file is sourced via the configure command, only the last SPAN
session ends up being created. This problem is fixed in software release 5.2(2)CSX.
(CSCdm23199)
• On 10/100 and 100 Mbps Ethernet switching modules with one or more EtherChannel trunks,
after entering set module power down and set module power up commands, occasionally the
spanning tree state is “not connected” for all but VLAN 1. To restore connectivity, reset the
module. This problem is fixed in software release 5.2(2)CSX. (CSCdm23329)
• When using the set port speed command to change from 100 to auto, channels on the port might
split. This problem is fixed in software release 5.2(2)CSX. (CSCdm23529)
• If IGMP is enabled, when a port in an EtherChannel to the MSM gets disabled, the switch stops
forwarding IP multicast traffic in groups learned on the switch to the MSM. To restore
transmission of IP multicast traffic to the MSM, disable and then enable the channel. This
problem is fixed in software release 5.2(2)CSX. (CSCdm24673)
• When you enter the show sprom chassis command, incorrect snmpOID and stackmib_oid values
might be displayed. This problem is fixed in software release 5.2(2)CSX. (CSCdm26092)
