Enabling Mixed Mode On A 7450 System - Alcatel-Lucent 7450 Basic System Configuration Manual

Enabling Mixed Mode on a 7450 System

To configure mixed mode support, 7750 SR IOM3-XPs, 7750 MDAs, or 7750 SR IMMs
must be installed in a 7450 ESS-7 or ESS-12 router that is running OS 8.0 or later. All
network interfaces must be migrated to ports on the 7750 SR cards.
The mixed mode state is then enabled by using the mixed-mode-upgrade command:
CLI Syntax:
This tool will take a list of slots that should have 7750 SR cards installed. The command then
checks to ensure that all network interfaces are located on ports on these slots and that they
are all 7750 SR cards. It then enables the mixed-mode state at the system level and changes
the capability setting for the specified slots to sr.
At this point the 7450 ESS system is operating in a mixed mode state and supported features
and services can now be configured on the slots with SR capabilities enabled.
Once in mixed mode use the capability command to configure slots for SR capabilities:
CLI Syntax:
Slots using 7750 SR-capable cards will have to have 7750 SR capability enabled on all slots
with 7750 SR IOM3s and IMMs, as well as mixed-mode at the system level.

• ESM for IPv6 must run on IOM-3 or IMM hardware only, not on IOM or IOM-2,
because the IOM and IOM2 data planes are not capable of routing incoming traffic
to the IPv6 ESM hosts.
• The scaling limits are still defined by the chassis mode. That means only 16k IPv6
ESM subscribers (limited by the ARP scale of chassis mode A).

basic principle of mixed versus non-mixed mode operation.
