7750 SR

Overview

The 7750 SR is a multi-service edge router designed for service providers, cable MSO, and enterprise customers that deliver residential, business and mobile services through an IP/MPLS network.

See the NSP NFM-P Network Element Compatibility Guide for supported SR variant information.

Ethernet port utilization summary

Ethernet ports on NEs using SR-OS display a summary of input and output port utilization on the Ethernet tab of the port configuration form. The summary is expressed as a percentage, and summarizes utilization over the interval specified in the Utilization Stats Interval parameter.

Automatic provisioning for CPM5 SFMs

The NFM-P automatically provisions and configures the integrated SFMs of CPM5s that feature built-in modules. The automated provisioning occurs during node discovery.

7450 ESS emulation

A 7750 SR node can be configured to operate in 7450 ESS emulation mode. While in emulation mode, the 7750 SR appears in the NFM-P as a 7450 ESS node, and supports 7450 ESS features and cards. See the 7750 SR node documentation for information about how to configure 7450 ESS emulation mode, and which variants of the 7750 SR support emulation.

ESA support

The Extended Services Appliance (ESA) operates as a resource server that provides packet buffering and processing, and is logically part of the 7750 SR router system. The ESA connects to the 7750 SR using standard SR interface ports, so all communication passes through the IOM, making use of the network processor complex on the host IOM for queuing and filtering functions, as with other MDAs and ISAs. The ESA hosts up to four Virtual Machine (VM) instances for multiservice processing.

See the NSP NFM-P Network Element Compatibility Guide for information about which SR devices support ESAs.

GNSS receiver support

All FP5-enabled SR NEs support integrated dual band GNSS receivers. The GNSS receiver supports GPS and GPS plus GLONASS. See To configure GNSS receiver functions on supported IXR and SR NEs for more information.

Discovering VSR-I using an AIM agent

The AirFrame Infrastructure Manager (AIM) is a proxy SNMP agent running on an AirFrame box in a VSR-I stack.

You need to initiate the discovery of the AIM in order to automatically discover the VSR-I . After the AIM for the VSR-I is discovered, the VSR-I is automatically added to the AIM discovery rule, so that the VSR-I is automatically discovered.

See To configure the AIM mediation and discovery for management of the VSR-I.
