Cisco References vol1
Cisco has a number of reference documents that are very useful in day to day network
consulting, but can be a real bear to find in a pinch.
The first is Cisco Unified Callmanager 4.1 TCP and UDP Port Usage. It goes through and
identifies all the TCP and UDP ports in use by the various Callmanager services. Ports are
grouped into the following categories:
- Intracluster Ports Between CallManagers
- Windows and Common Ports
- Between CallManager and LDAP Directory
- Web Requests from CCMAdmin or CCMUser to CallManager
- Signalling, Media and Other Communications Between Phones and Callmanager
- PC Behind the Phone to the Phone
- Signalling, Media and Other Communications Between Gateways and Callmanager
- Communications Between Applications and CallManager
The end of the document contains a number of links regarding PIX and IOS FW Inspection
and Context Based Access Control.
When trying to select a Cisco device 'based on the numbers', you'll want to take a look
at Cisco's Portable Product Sheets. The key sheets have to do with
performance of the various switch models and router models. In addition, there are sheets
relating to Port Adaptors, NM/WIC/VWIC compatibility, VPN performance, wireless comparisons,
some info on GBICS, as some stuff on phones and voice density.
Cisco's TAC Tools page has such things as a DSP Calculator, IP Subnet
Calculator, and a Voice Codec Bandwidth Calculator.
