Chapter 2: New in this release

The following sections detail what is new in Troubleshooting Avaya Ethernet Routing Switch 4000
Series, NN47205-700 for Release 5.7.

Features

See the following sections for information about features changes:

SLA Monitor

The Service Level Agreement (SLA) Monitor feature is implemented phase-wise on the ERS
4000 series switch. In Release 5.6, the phase 1 implementation included the feature, SLA
Monitor on the ERS 4000 series switch and supported only non-secure agent-server
communication.
In Release 5.7, phase 2 implementation ensures a secure SLA Monitor agent-server
communication through certificate-based authentication and encrypted agent-server
communication. Also, SLA Monitor agent can perform QoS tests in the absence of SLA Monitor
server using the platform CLI.
For more information about SLA Monitor agent, see:

NN47205-502.

802.3at LLDP based discovery

ERS 4000 Series PWR+ devices support the IEEE 802.3at-2009 standard for an Link Layer
Discovery Protocol (LLDP) configuration with a Powered Device (PD). The LLDP support for
PoE+ is added by extending the existing standard LLDP DOT3 Power via MDI TLV defined by
the IEEE 802.1ab with the new fields and values defined in the IEEE 802.3at-2009 standard.
Information for power negotiation between PD and Power Sourcing Equipment (PSE) is
described in Power via MDI, which is an optional 802.1AB TLV.
