Ipv6 Management - Avaya 4524GT Configuration Manual

System configuration fundamentals
address to ensure that all devices on the management VLAN have their ARP caches
appropriately updated.
Stack Forced Mode allows non-EAP clients connected to the device to still authenticate
themselves and maintain connectivity to the network. Non-EAP clients authenticate by the
device with RADIUS, which is based on the stack IP address. In Stack Forced Mode, the device
retains the IP settings of the stack of two.
The functional unit stays in Stack Forced Mode until either a reboot or it joins a stack.
A settlement timer prevents several stack failures that occur at an interval of a few seconds to
lead to a device entering Stack Forced Mode after it was part of a stack larger than two units.
A device enters Stack Forced Mode if and only if it was part of a stack of two for 30 seconds
or longer.
If the switch is in Stack Force mode and you want to set a switch IPv6 address, you must first
delete the active IPv6 interface and then configure the switch IPv6 address. If you use Telnet,
SSH or EDM to change the settings, the switch will lose IPv6 connectivity to the switch. Avaya
recommends that you change the settings with the Console Interface to switch or use an IPv4
address for management.

IPv6 management

This module provides information about the IPv6 management feature of the Avaya Ethernet
Routing Switch 4500 Series switch platform.
IPv6 Management allows the user to configure an IPv6 address on the management VLAN.
This enables IPv6 connectivity. The management VLAN can have both an IPv4 and an IPv6
address configured simultaneously (Avaya Ethernet Routing Switch 4500 functions as a dual
stack network node).
There is no IPv6 routing support in the current phase and therefore only one IPv6 interface is
associated to the management VLAN. You can only perform IPv6 interface configuration
(enabling, assigning IPv6 address and prefix, changing other parameters, querying interface
statistics) from ACLI or through SNMP (EDM).
IPv6 Management adds support for new standard MIBs (IP-MIB—RFC 4293, TCP-MIB—RFC
4022, UDP-MIB—RFC 4113) as well as the enterprise MIB rcIpv6.
If the switch is in Stack Force mode and you want to set a switch IPv6 address, you must first
delete the active IPv6 interface and then configure the switch IPv6 address. If you use Telnet,
SSH, or EDM to change the settings, the switch will lose IPv6 connectivity to the switch. Avaya
recommends that you change the settings with the Console Interface to switch or use an IPv4
address for management.
