Release Notes for Catalyst 4500 Series Software Release 7.x
OL-1983-28
Open and Resolved Caveats in Software Release 7.2(1)
• When connected to a dynamic port, the IP phone cannot register with Cisco Call Manager.
Workaround: To initially connect an IP phone, you must include the MAC address of the IP phone
in the VMPS text file. If the IP phone is connected to your PC, you must assign the same VLAN for
both the IP phone and the PC, or you might configure the IP phone to a fallback VLAN. Configuring
the IP phone to a fallback VLAN will decrease the security level of your network. This problem is
resolved in software release 7.2(1). (CSCdw71503)
• HP TopTool Remote Control Card v2.0 will join or leave the group approximately every 1 minute.
This problem is resolved in software release 7.2(1). (CSCdw00897)
• A router in HSRP standby status is changed to active status. When status is restored, it does not go
back to standby status from active status.
Workaround: The router recovers if the interface on the HSRP standby side is set to shutdown or
no shutdown. This problem is resolved in software release 7.2(1). (CSCdw32957)
• MST is not converging in networks with more than 200 VLANs, or in networks involving a
Catalyst 4500 series switch running MST where a lot of topology changes are observed. This
problem might happen if the switch is running software release 7.1(1) and the switch repeatedly
flushes its dynamic CAM. This problem is resolved in software release 7.2(1). (CSCdw39902)
• The switch might crash if VTP is configured in client or server mode and connected to a
Catalyst 4500 series switch with a Supervisor Engine III.
Workaround: Configure VTP to use transparent mode. This problem is resolved in software release
7.2(1). (CSCdw41158)
• In certain configurations, the switch might drop IGMP reports before passing the reports to the
router. If multicast functionality is based on CGMP, it will be affected.
Workaround: Manually add a multicast static entry pointing to the CGMP router on the switch that
is dropping IGMP reports. This problem is resolved in software release 7.2(1). (CSCdw60550)
• If you configure the switch with one trunk and 256 VLANs, the switch should handle 17,000 MAC
addresses. Because the memory is shared, you cannot benchmark the maximum number of MAC
address entries or VLANs. If the switch is configured with more than one trunk or more than
256 VLANs, you might see this error message:
Failed to download VMPS configuration file.

The maximum size of the VMPS text configuration file that can be successfully downloaded by the
VMPS server is 915,456 bytes. If the file is larger than 915,456 bytes, this error message is
displayed:
TFTP connection fail(-1).

This problem is resolved in software release 7.2(1). (CSCdw93962)
