What’s New In ArubaOS 6.2
The following features have been added in the ArubaOS 6.2 release:
Feature Description
LLDP
Link Layer Discovery Protocol (LLDP), is a Layer-2 protocol that allows network
devices to advertise their identity and capabilities on a LAN. Wired interfaces on Dell
APs support LLDP by periodically transmitting LLDP Protocol Data Units (PDUs) com-
prised of type-length-value (TLV) elements.
Capacity monitoring
The controller will send a
wlsxThresholdExceeded
SNMP trap and a syslog error
message when the controller has exceeded a set percentage of the total capacity for
that resource. A
wlsxThresholdCleared
SNMP trap and error message will be trig-
gered if the resource usage drops below the threshold once again.
Bandwidth contract support for
Remote APs
Configure bandwidth contracts for a remote AP on a per-role or per-user basis.
Protection against DHCP address
exhaustion attack
This feature checks the frame's source-MAC against the DHCPv4 client hardware
address and drops the packet if it does not match.This prevents a client from sub-
mitting multiple DHCP requests with different hardware addresses, which can
deplete the DHCP pool.
L3 Mobility Support in VRF
Environments
The L2-GRE Tunnel implementation of the IP mobility functionality is supported only
on ArubaOS versions 6.2 or later and is not backward compatible with the earlier
implementation. ArubaOS supports only v4 mobility and does not support IPv6 L3
mobility.
