Caveats
Workarounds:
– Do not inject packets that require an IP redirect sent out to an IP unnumbered port within 3
minutes of booting the Catalyst 4500 series switch.
– Configure the correct default gateway on the host side. (CSCse75660)
•
When policing IEEE 802.1Q tagged non-IP traffic and calculating traffic conformance, the policer
excludes the four bytes that constitute the 802.1Q tag even when you enter the
qos account layer2 encapsulation command.
Workaround: None. (CSCsg58526)
•
When hard-coded duplex and speed settings are deleted after an interface shuts down, an a- is added
to the duplex and speed in the output from the show interface status command.
This does not affect performance.
Workaround: Enter the no shutdown command. (CSCsg27395)
•
When a transceiver is removed rapidly from one port and placed in another on the same chassis,
occasionally a duplicate seeprom message appears and the port is not able to handle traffic.
Workaround: Remove the transceiver from the new port and place it in the old port. After the SFP
is recognized in the old port, remove it slowly and insert it in the new port. (CSCse34693).
•
When performing an ISSU upgrade and the versions of the active and standby supervisor engines
differ, you see the following message in the standby supervisor engine console:
%XDR-6-XDRINVALIDHDR: XDR for client (CEF push) dropped (slots:2 from slot:3
context:145 length:11) due to: invalid context
Workaround: None. This is an informational message. (CSCsi60898)
•
When you send traffic on a VLAN ID higher than 3000, the convergence timing caused by a failure
exceeds 225 ms.
Workaround: None. (CSCsm30320)
•
An IP unnumbered configuration is lost after a switch reloads.
Workarounds: Do one of the following:
– After a reload, copy the startup-config to the running-config.
– Use a loopback interface as the target of the ip unnumbered command.
– Change the CLI configuration so that during bootup the router port is created first.
(CSCsq63051)
•
In SSO mode, when a port channel is created, deleted, and recreated on an active supervisor engine
with the same channel number, the standby port channel state goes out of sync. After a switch over,
the following message displays:
%PM-4-PORT_INCONSISTENT: STANDBY:Port is inconsistent:
Workaround: When the port channel starts to flap, enter shut and no shut on the port channel. After
the first switchover and after deleting the port channel, create a new channel. (CSCsr00333)
•
When you configure ip source binding statically on an interface, and then remove linecard on which
the interface resides, the entries are not removed from the running configuration.
Workaround: Before removing a line card, delete the statically configured ip source binding
entries on any of the interfaces on the line card. (CSCsv54529)
•
If you configure OFM on an EtherChannel (with at least two interfaces), when you shut or remove
the first member that joined the channel, you lose the CFM neighbor.
