Release Notes for the Cisco Catalyst Blade Switch 3020 for HP, Cisco IOS Release 15.0(2)SE and Later

OL-27324-02

Resolved Caveats

• CSCuh51379

When VTp mode is set to transparent and vlan.dat file present in flash is deleted, after reload, access

vlan is not configured in the switch even though vlan configuration is present in running config or

startup config.

The workaround is to set the vtp mode to server or client.

• CSCuj81498

The internal port links between 3020 switches and blade servers do not work when you start the

switch and the server with a specific power on and off sequence.

The workaround is to restart the switch.

• CSCto13462

In a network that consists of two DHCP clients with same client id and different mac addresses, the

DHCP server reloads when one of the clients releases its DHCP address.

There is no workaround.

• CSCts80209

A switch configured with login quiet-mode resets when you enter the login block-for or no login

block-for commands.

There is no workaround. To avoid a reset, do not enter the login block or no login block-for

command.

switch virtual interface.
