Chapter 3 Preparing to Use Campus Manager
Setting Up Campus Manager Applications
Setting Up Path Analysis
To set up Path Analysis:
Step 1 Install and configure a DNS server on your network.
A DNS server is required for Campus Manager. For devices with multiple IP
addresses, there should be a single DNS entry that includes all IP addresses.
Step 2 Specify correct read community strings on all devices.
Step 3 Specify correct write community strings for multi-layer switching shortcut path
determination on Catalyst 5000 devices.
Step 4 Edit the VLAN/ELAN Mapping Table, which provides mapping of VLANs and
ELANs to subnets.
These mappings are auto-discovered based on information gathered by Topology
Services and User Tracking.
In some cases, the information might be incomplete. In these cases, you can edit
a VLAN/ELAN mapping table to supplement the Topology Services and User
Tracking information. If subnet mappings are not correct, Layer 2 traces on those
subnets might fail.
Step 5 Enable Cisco Discovery Protocol (CDP) on all Cisco devices.
If CDP is not enabled, these devices will not appear on Layer 2 path traces.
Step 6 Enable source routing on your network.
This is required if you plan to run path traces outside of the domain known to
Topology Services.
