PowerConnect 8132/8164/8132F/8164F/8024/8024F/M8024/M8024-k/ M6220/M6348/7024/7048/7024P/7048P/7024F/7048R/7048R-RA Release Notes The operator has the ability to enable DHCP Relay Information Options both globally and on a physical interface. The interface configuration overrides the global configuration for the selected interface. Relay Information Option Check: When DHCP Option-82 insertion is enabled for a relay agent, the server should echo received Option 82 unaltered back toward the client. The relay agent is required to strip Option 82 information before relaying the BOOTPREPLY to the DHCP client. When enabled, the Relay Information Option Check will cause the BOOTPREPLY packet to be dropped if invalid sub-options are echoed by the DHCP server.  L2 Address Table The administrator can disable MAC address table aging. The administrator can configure static forwarding of a MAC address on a specific VLAN. NOTE: By default, multicast frames are flooded by the switch. Utilize the mac address-table multicast filtering command to disable flooding of multicast frames.  LLDP Enhancements Multiple Neighbor Support: Multiple neighbors are supported on a single LLDP interface. The number of recognized neighbors is limited to two per port or 834 LLDP neighbors on a fully stacked set of switches. There is no restriction on the number of neighbors connected to an LLDP port. If more LLDP neighbors are present than are supported, then only the last two neighbors that communicate with the local LLDP interface are recognized and any additional neighbors are ignored. EEE Support: Support is added to process/communicate the EEE TLV to partner devices. The EEE TLV is an 802.3 organizationally specific TLV used to report on the EEE Data Link Layer capabilities. LLDP-MED Support: LLDP-MED uses LLDP's organizationally specific TLV extensions and defines new TLVs which make it easier to deploy VoIP in a wired or wireless LAN/MAN environment. The LLDP implementation supports the following TLVs: Mandatory 802.1AB TLVs • Chassis ID TLV (subtype shall default to MAC Address) • Port ID TLV (subtype shall default to MAC address • TTL TLV • MAC/PHY configuration/status TLV • End of LLDP PDU Optional 802.1AB TLV • Systems Capabilities TLV • Power via MDI TLV NOT recommended for transmission in order to conserve LLDPDU space.

Release Notes
System Firmware Version 5.1.0.1

The operator has the ability to enable DHCP Relay Information Options both globally and on a physical interface. The
interface configuration overrides the global configuration for the selected interface.
Relay Information Option Check:
When DHCP Option-82 insertion is enabled for a relay agent, the server should echo received Option 82 unaltered back
toward the client. The relay agent is required to strip Option 82 information before relaying the BOOTPREPLY to the
DHCP client.
When enabled, the Relay Information Option Check will cause the BOOTPREPLY packet to be dropped
if invalid sub-options are echoed by the DHCP server.
L2 Address Table
The administrator can disable MAC address table aging.
The administrator can configure static forwarding of a MAC address on a specific VLAN.
NOTE:
By default, multicast frames are flooded by the switch. Utilize the
mac address-table multicast filtering
command to disable flooding of
multicast frames.
LLDP Enhancements
Multiple Neighbor Support:
Multiple neighbors are supported on a single LLDP interface. The number of recognized neighbors is limited to two
per port or 834 LLDP neighbors on a fully stacked set of switches. There is no restriction on the number of neighbors
connected to an LLDP port. If more LLDP neighbors are present than are supported, then only the last two neighbors
that communicate with the local LLDP interface are recognized and any additional neighbors are ignored.
EEE Support:
Support is added to process/communicate the EEE TLV to partner devices. The EEE TLV is an 802.3 organizationally
specific TLV used to report on the EEE Data Link Layer capabilities.
LLDP-MED Support:
LLDP-MED uses LLDP’s organizationally specific TLV extensions and defines new TLVs which make it easier to
deploy VoIP in a wired or wireless LAN/MAN environment. The LLDP implementation supports the following TLVs:
Mandatory 802.1AB TLVs
•
Chassis ID TLV (subtype shall default to MAC Address)
•
Port ID TLV (subtype shall default to MAC address
•
TTL TLV
•
MAC/PHY configuration/status TLV
•
End of LLDP PDU
Optional 802.1AB TLV
•
Systems Capabilities TLV
•
Power via MDI TLV
NOT recommended
for transmission in order to conserve LLDPDU space.
