Overview

NE maintenance

The NFM-P has policies and functions that facilitate the maintenance of managed NEs. You can use the NFM-P to do the following:

• configure how and when to deploy NE configuration changes—see Chapter 25, NE deployment

• back up device configurations on demand, or using a schedule—see Chapter 23, NE backup and restore

• restore device configurations—see Chapter 23, NE backup and restore

• perform device configuration rollbacks—see Chapter 24, NE configuration rollback

• upgrade device software on demand, or using a schedule—see Chapter 24, NE configuration rollback

• monitor and troubleshoot operations in progress

• browse NE file systems—see To view an NE file system using an FTP file browser and To view an NE file system using an SSH file browser

You can also view the accounting statistics collection status of an NE using To view the accounting statistics collection status of an NE , and view the SNMP trap metrics of an NE using To view NE trap metrics information .

NE file system browsing

An NFM-P operator can browse the file system of a managed NE to list the contents of the compact flash devices. You can browse the file system of a 7210 SAS, 7450 ESS, 7705 SAR, 7750 SR, 7950 XRS, or OmniSwitch using simple FTP or a CLI session using SSH. The NFM-P GUI is used to browse the different types of files.

Note: Some 7210 SAS devices are equipped with a USB flash memory (uf1). In the equipment tree and on Alarm Info forms, the NFM-P displays only Flash Memory. The display does not distinguish between compact flash memory (cf) and USB flash memory (uf).

Browsing an NE file system using the NFM-P is a convenient way to confirm that operations such as the following occur as planned by verifying the sizes and time stamps of local NE files:

• NE configuration saves

• NE software image transfers and upgrades

• NE configuration restores

• NE accounting-statistics collection

FTP file browsing on an NE requires FTP user account access on the NE. SSH file browsing requires console user-account access and the configuration of SSH security on the NE. See Chapter 8, Device commissioning and management for information about enabling FTP and console access for an NE user and configuring SSH on an NE.

Note: A 7705 SAR may become temporarily unreachable while enabling SSH and starting the device SSH server.
