Cache Mode: Opening a Configuration File
Cache mode addresses the problem of long response times that may be
encountered while configuring a router in dynamic mode, while still providing
real-time configuration to the target router.
In dynamic mode, Site Manager uses SNMP set operations to write directly to the
routers management information base (MIB), and thus provide real-time
configuration. However, before issuing an SNMP
set
command, Site Manager
may have to read several MIB items from the router using SNMP get operations.
Long response times in dynamic mode are caused mainly by the large number of
SNMP retrievals (get operations) that precede the SNMP set.
To improve response time, cache mode saves a copy of the routers existing
operational configuration to a local file on the Site Manager workstation. Site
Manager then uses this local file to obtain MIB values. Site Manager also updates
the local file to reflect any dynamic changes made during the cache mode
configuration session. Consequently, the local copy of the routers configuration
always mirrors the routers operational state.
To open a configuration file in cache mode:
1. In the Site Manager main window, connect to the router you want to
configure.
See Chapter 1, Getting Started with Site Manager, for instructions.
