Release M.08.94 Enhancements

The current QoS Pass-Through Mode also is displayed in the show running-configcommand output.

Operating Notes

■To use the same QoS queue structure used in pre-M.08.78 software, set the QoS Pass-Through Mode to balanced.

■The optimized mode matches the QoS Pass-through mode on the ProCurve Series 2800 switches. This mode is used when the QoS Pass-Through Mode command is entered with no arguments, qos-passthrough-mode.

Release M.08.94 Enhancements

Release M.08.94 includes the following enhancements:

■Added DHCP Option 82 functionality for 3400cl series.

■UDP broadcast forwarding feature is now supported on the 3400cl series.

DHCP Option 82: Using the Management VLAN IP Address for the Remote ID

This section describes the Management VLAN enhancement to the DHCP option 82 feature. For more information on DHCP option 82 operation, refer to “Configuring DHCP Relay” in the chapter titled “IP Routing Features” in the Advanced Traffic Management Guide.

When the routing switch is used as a DHCP relay agent with Option 82 enabled, it inserts a relay agent information option into client-originated DHCP packets being forwarded to a DHCP server. The option automatically includes two suboptions:

■Circuit ID: the identity of the port through which the DHCP request entered the relay agent

■Remote ID: the identity (IP address) of the DHCP relay agent

Using earlier software releases, the remote ID can be either the routing switch’s MAC address (the default option) or the IP address of the VLAN or subnet on which the client DHCP request was received. Beginning with software release M.08.xx, if a Management VLAN is configured on the routing switch, then the Management VLAN IP address can be used as the remote ID.
