Release Notes

20 System Firmware Version 5.1.1.7
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.
Mandatory LLDP-MED TLVs
• LLDP-MED Capabilities TLV
This TLV allows the network connectivity device to definitively determine whether particular connected
devices do support LLDP-MED and to discover which specific LLDP-MED TLVs the particular end point
devices are capable of supporting as well as what specific device class they belong to.
• Network Policy TLV
This TLV allows the device to advertise its VLAN and associated Layer 2 priority and Layer 3 DSCP
attributes which apply for a set of specific protocol applications on this port.
• Location Identification TLV
This TLV provides the advertisement of location identifier information Class II endpoint Devices. This is
expected to be related to wire map or similar network topology data, such that the configuration of the
network Connectivity device is able to uniquely identify the physical location of the connected MED
endpoint.
• Extended Power-via-MDI TLV
This TLV allows for advanced power management between endpoints and network connectivity devices. It
transmits fine grained power requirement details. This TLV provides significantly more value than the
802.1AB Power via MDI TLV.
• EEE TLV
The EEE TLV is used to exchange information about the EEE Data Link Layer capabilities. Devices that
require longer wake up times prior to being able to accept data on their receive paths may use the Data Link
Layer capabilities to negotiate for extended system wake up times from the transmitting link partner. This
mechanism may allow for more or less aggressive energy saving modes.
 Dynamic VLAN Assignment
Dynamic VLAN assignment is intended to support the connection of hosts to a router with enhanced levels of service,
typically either security or QoS. This release supports dynamic VLAN assignment as assigned from the RADIUS
server as part of port authentication. The following additional checks are performed in support of dynamic VLAN
assignment:
Before assigning the port to RADIUS assigned VLAN, dot1x checks if the given VLAN is in the VLAN database or
not. If the assigned VLAN is not in the VLAN database and dynamic VLAN assignment is enabled, a VLAN is
created on the port over which the client is authenticated. Each time a client is de-authenticated on an interface with a
particular VLAN, a check verifies if there any other interface which a VLAN member is. If there is no interface as a
member, the VLAN is deleted. This behavior is same for MAC based authentication as well.
 Usability Enhancements
In the output of the show running-config command, the slot and member configuration is commented with the
switch/slot type in human comprehensible form.
When in interface config mode, CLI users can navigate to a different interface by entering the appropriate interface
command without leaving interface config mode.
CLI users can log out of the switch using the exit command (exit is an alias for quit).
The CLI Reference Guide is updated with acceptable character sets and maximum lengths for string parameters to
commands.
Management ACLs permit specification of service any as shorthand for enabling all services access for in-band
management.
