CoreWatch User’s Guide 21
Chapter 1: A Look at CoreWatch
– Check the status of each bridge table, routing table, and QoS table. These tables
contain information that CoreWatch obtains from MIBs it supports. (For a list of
these MIBS, see
“Which MIBs Does the SSR Support?” on page 21 .)
– Display messages stored in the SSR boot log.
– SNMP is a protocol that provides support for monitoring and controlling network
devices, collecting statistics, and managing configurations, performance, and
security. SNMP is mainly used by Transmission Control Protocol/Internet Protocol
(TCP/IP) networks. (TCP/IP is a suite of protocols that provide a relatively simple
way to connect computers and devices from different vendors on a worldwide
internetwork.)
CoreWatch displays most monitoring information in tables and reports, but there is some
data that is displayed in the form of graphs or dials.
A Look at the Modes of CoreWatch
CoreWatch can run in the following modes:
• User, which is the mode CoreWatch automatically begins operating in after you log in
to CoreWatch. Use this mode to monitor the activity on the SSR or to obtain reports.
• Configure, which is the mode you use to perform any of the following tasks:
– Change system information
– Configure bridging and VLANs
– Set QoS policies
– Set security filters
• Configure multiple configuration databases as discussed later in this guide
You switch to the configure mode by starting Configuration Expert. Access to
Configuration Expert is controlled by a password that your system administrator can set
as discussed in
“Changing the Privileged Password” on page 32 .
Which MIBs Does the SSR Support?
CoreWatch obtains information from MIBs when displaying the CoreWatch tables
discussed later in this guide. The SSR supports the following MIBs:
• IETF Standard MIBs:
MIB2/RFC 1213 (r/w to system group and to snmpEnableAuthTraps only)
• IETF Draft Standard MIBs:
– OSPF-MIB/RFC 1850
