Release Notes
System Firmware Version 5.1.1.7 Page 19
Fragmentation and reassembly of VRRP packets is not supported.
 DHCP Relay
The following enhancements have been made to the operation of DHCP Relay to bring the implementation into
conformance with RFC 4649:
DHCPv6 Relay Circuit Id/Remote Id Types
RFC 4649 specifies the IANA assignment of the Relay Circuit Id sub-option and Remote Id option. The
implementation has been changed so that the administrator can no longer assign a numerical value to these TLVs as the
IANA assigned number is now used. The administrator can still enable or disable the insertion of these TLVs in
messages sent to the DHCP server.
Relay Information Option:
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:
