Open and Resolved Caveats in Software Release 5.5(10)

These sections describe the open and resolved caveats in software release 5.5(10).

•Open Caveats in Software Release 5.5(10)

•Resolved Caveats in Software Release 5.5(10)

Open Caveats in Software Release 5.5(10)

This section describes the open caveats in software release 5.5(10):

•On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired). (CSCdk31747)

Resolved Caveats in Software Release 5.5(10)

This section describes resolved caveats in software release 5.5(10):

•A physical connection may be detected for certain 1000BASE-SX GBICs when they are inserted in a Gigabit EtherChannel module (WS-X5410) with no fiber cable attached. An automatic corrective action restores the port to unconnected status; however, the LED on an SX GBIC may go on and off.

Workaround: Disable the port when it is not in use. This problem is resolved in software release 5.5(10). (CSCdm63410)

•Under extremely rare conditions, a switch port may lose the VLAN configuration. An affected trunk port transmits all traffic in an untagged mode in the native VLAN. Connectivity to the rest of the network may be impacted if the affected port is an uplink port. Spanning Tree Protocol (STP), Cisco Discovery Protocol (CDP), and other traffic continues to operate normally. This problem is resolved in software release 5.5(10). (CSCdu48749)

Open and Resolved Caveats in Software Release 5.5(8)

These sections describe the open and resolved caveats in software release 5.5(8).

•Open Caveats in Software Release 5.5(8)

•Resolved Caveats in Software Release 5.5(8)

Open Caveats in Software Release 5.5(8)

This section describes open caveats in software release 5.5(8):

•On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired). (CSCdk31747)

Resolved Caveats in Software Release 5.5(8)

This section describes resolved caveats in software release 5.5(8):

•This fix was made in the supervisor engine software but is related to the Gigabit EtherChannel module. The Catalyst 5500 series switch might crash during a Telnet session between the switch and the RSM. This situation might occur when the switch has the following modules installed together: RSM, Token Ring, and Gigabit EtherChannel.

Workaround: Reset the switch. This problem is resolved in software release 5.5(8). (CSCdt01088)

Open and Resolved Caveats in Software Release 5.5(7)

These sections describe the open and resolved caveats in software release 5.5(7).

•Open Caveats in Software Release 5.5(7)

•Resolved Caveats in Software Release 5.5(7)

Open Caveats in Software Release 5.5(7)

This section describes open caveats in software release 5.5(7):

•On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired). (CSCdk31747)

Resolved Caveats in Software Release 5.5(7)

This section describes resolved caveats in software release 5.5(7):

•Occasionally, when you enter the show cam dynamic command or issue an snmp host query, you might see the following system message:

SYS-4-P2_WARN: 1/Filtering Ethernet MAC address of value zero from agent host table interface

This message indicates that the switch received a packet from a network device with the MAC address 00-00-00-00-00-00. This address is noncompliant and is filtered from the show cam dynamic command output. The clear cam dynamic command failed to clear this MAC address from the switch's host table. This caveat does not affect the operation of the switch in any way. This problem is resolved in software release 5.5(7). (CSCds69706)

Open and Resolved Caveats in Software Release 5.5(3)

These sections describe the open and resolved caveats in software release 5.5(3):

•Open Caveats in Software Release 5.5(3)

•Resolved Caveats in Software Release 5.5(3)

Open Caveats in Software Release 5.5(3)

This section describes open caveats in software release 5.5(3):

•On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired). (CSCdk31747)

•Occasionally, when you enter the show cam dynamic command or issue an snmp host query, you might see the following system message:

SYS-4-P2_WARN: 1/Filtering Ethernet MAC address of value zero from agent host table interface

This message indicates that the switch received a packet from a network device with the MAC address 00-00-00-00-00-00. This address is noncompliant and is filtered from the show cam dynamic command output. The clear cam dynamic command failed to clear this MAC address from the switch's host table. This caveat does not affect the operation of the switch in any way. This problem is resolved in software release 5.5(7). (CSCds69706)

Resolved Caveats in Software Release 5.5(3)

This section describes resolved caveats in software release 5.5(3):

•Many protocols implemented on the Catalyst 5000 family switches (for example, CGMP) require the port location of a particular MAC address. To determine the port location, the Host Table usually needs to be sorted through because SNMP getNext operations use a host's MAC address as an index in the table. This operation is not required to determine the port location of a specific MAC address but is performed anyway. This problem is resolved in software release 5.5(3). (CSCdp90079)

Open and Resolved Caveats in Software Release 5.4(1)

These sections describe the open and resolved caveats in software release 5.4(1):

•Open Caveats in Software Release 5.4(1)

•Resolved Caveats in Software Release 5.4(1)

Open Caveats in Software Release 5.4(1)

This section describes open caveats in software release 5.4(1):

•On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired). (CSCdk31747)

•Occasionally, when you enter the show cam dynamic command or issue an snmp host query, you might see the following system message:

SYS-4-P2_WARN: 1/Filtering Ethernet MAC address of value zero from agent host table interface

This message indicates that the switch received a packet from a network device with the MAC address 00-00-00-00-00-00. This address is noncompliant and is filtered from the show cam dynamic command output. The clear cam dynamic command failed to clear this MAC address from the switch's host table. This caveat does not affect the operation of the switch in any way. This problem is resolved in software release 5.5(7). (CSCds69706)

Resolved Caveats in Software Release 5.4(1)

This section describes resolved caveats in software release 5.4(1):

•A sync-loss error might display this message:

6/C5man:Gigmac Link A, Mac rcv sync loss error, status reg is:0x00

This message refers to the 802.3z gigabit synchronization that occurs on the internal interface where the Gigabit Ethernet module connects to the switch backplane. In most cases, the synchronization will be reestablished after you see this message. If this message appears frequently, the module resets and performs power-on self-tests (POST). If a POST diagnoses an error, the module is kept offline so that any existing network redundancies can be activated by the Spanning Tree Protocol and spanning tree algorithm. (CSCdp33738)

•When you configure SPAN for a port or VLAN, neither transmitted nor received spanning tree BPDUs are mirrored to the SPAN destination port. (CSCdm47129)

Open and Resolved Caveats in Software Release 5.2(4)

These sections describe the open and resolved caveats in software release 5.2(4):

•Open Caveats in Software Release 5.2(4)

•Resolved Caveats in Software Release 5.2(4)

Open Caveats in Software Release 5.2(4)

This section describes open caveats in software release 5.2(4):

•On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired). (CSCdk31747)

Resolved Caveats in Software Release 5.2(4)

This section describes resolved caveats in software release 5.2(4):

There are no resolved caveats in software release 5.2(1).

Open Caveats in Software Release 5.1(1)

This section describes open caveats in Gigabit EtherChannel module software release 5.1(1).

•On the Gigabit EtherChannel module (WS-X5410), if a host allowed on one secured port is moved to another previously unused secured port on the same module, the host cannot connect to the network on the second port.

Workaround: Disable port security on the first port, move the host to the second port, and then reenable port security on the first port (if desired). (CSCdk31747)

•When you configure SPAN for a port or VLAN, neither transmitted nor received spanning-tree BPDUs are mirrored to the SPAN destination port. (CSCdm47129)

Usage Guidelines, Restrictions, and Troubleshooting

This section describes usage guidelines, restrictions, and troubleshooting information that applies to the Gigabit EtherChannel switching module.

•The link on a Gigabit EtherChannel module (WS-X5410) port with a 1000BASE-SX GBIC might go up and down even when there is no cable attached. You can disable the port when it is not in use to prevent the link from going up and down. (CSCdm63410)

•Use of the Gigabit EtherChannel module requires Catalyst 5000 family supervisor engine software release 4.2(1) or later with Gigabit EtherChannel module software release 4.2(1) or later.

•If you plan to use the Gigabit EtherChannel module in a Catalyst 5000 switch chassis or with Supervisor Engine I or II, use Gigabit EtherChannel module software release 4.3(1) or later with supervisor engine software release 4.3(1) or later. Prior to software release 4.3(1), the Gigabit EtherChannel module was not fully tested with this hardware.
