Enabling Custom Autonegotiation Advertisement (Cana) In Acli; Displaying The Current Autonegotiation Advertisements In Acli - Avaya 3500 series Getting Started

Managing Ethernet ports using ACLI
In certain situations, it is useful to autonegotiate a specific speed and duplex value. In these
situations, the switch can allow for attachment at an operating mode other than its highest
supported value.
For example, if the switch advertises only a 100 Mbps full-duplex capability on a specific link,
the link goes active only if the neighboring device is also capable of autonegotiating a 100
Mbps full-duplex capability. This prevents mismatched speed and duplex modes if customers
disable autonegotiation on the neighboring device.
Important:
The CANA feature is available for 10/100 Ethernet ports of ERS 3526T switches, and
10/100/1000 ports on the ERS 3510GT and ERS 3524GT switches (not available for rear
ports).

Enabling Custom Autonegotiation Advertisement (CANA) in ACLI

You can control the capabilities that are advertised by the Ethernet Routing Switch as part of
the auto-negotiation process using the Custom Autonegotiation Advertisements (CANA)
feature. After autonegotiation is disabled, the hardware is configured for a single (fixed) speed
and duplex value. After auto-negotiation is enabled, the advertisement made by the switch is
a constant value based upon all speed and duplex modes supported by the hardware. After
auto-negotiating, the switch selects the highest common operating mode supported between
it and its link partner.
