Release Notes

Release Notes for the Catalyst 4500E Series Switch, Cisco IOS XE Release 3.3.xSG

OL-26675-02

Caveats

The power supply or power supply inputs are incorrectly listed as 110V when they should be list as

220V. The power supply may go into an err-disable state if only one power supply has the issue. If

both power supplies have the issue and are both recognized as 110V, they will not go into an

err-disable state. Additionally, other modules in the switch might be denied power and will not

power on.

Workaround: Remove the power supply inputs, remove or reinsert the power supply, then restore

the power supply inputs. CSCuc07562

• An ISSU upgrade from Cisco IOS XE 3.2.5SG to 3.3.1SG fails.

However, you can perform an upgrade from Cisco IOS XE 3.2.5SG to 3.3.2SG or from Cisco IOS

XE 3.2.5SG to 3.4.0SG.

Workarounds:

–

Use RPR for Cisco IOS XE 3.2.5SG or 3.3.1SG combinations (upgrade or downgrade).

–

Downgrade from Cisco IOS XE 3.3.1SG; using 3.2.4SG or an earlier release.

–

Upgrade from Cisco IOS XE 3.2.5SG; use 3.3.2SG instead.

300 bytes).

Workaround: Disable CDP on interfaces that may flap frequently. CSCub85948

Resolved Caveats for Cisco IOS XE Release 3.3.1SG

This section lists the resolved caveats for Cisco IOS XE Release 3.3.1SG:

• When a QoS policy is attached to a physical interface on a module or to a channel port containing

interfaces on the module, a crash may occur when you remove a line card.

Workaround: Remove the QoS policy before removing the linecard. CSCtz39815

• On a switch running Cisco XE 3.2.4SG or 3.3.0SG with 4648* or 4748* linecards with PoE, a single

port on a linecard fails to link up, usually after flapping its link frequently.

Workaround: Enter shut then no shut on the port. CSCtz94862

• On a switch running Cisco XE 3.2.4SG or 3.3.0SG on 4648* or 4748* linecards with PoE, the PoE

device will not power up on a single port, but will work on other ports on the same linecard.

Workarounds:

–

Connect a non-PoE device to the port
