CalREN Backbone FAQs: General Information

Network Management

CENIC employs many automated network management tools to assist our Associates in the planning and management of their own networks, including Intermapper, Rancid, RT, and Cricket.

DC Router Naming Conventions

Function	Name	Example	Model	Notes
Core routing	site-CORE or site-CORE{1,2}	RIV-CORE	Cisco CRS-1	Backbone circuits only, no customer-facing connections
High-speed aggregation	site-AGG{1,2}	FRG-AGG1	Cisco GSR
Low-speed aggregation	site-AGG3	OAK-AGG3	Cisco 7200	T-1, some T-3 circuits
ISP transit	site-ISP or site-ISP{1,2,...}	SVL-ISP	Cisco GSR	ISP transit links and dedicated transit waves
Peering	site-PX or site-PX{1,2,.}	LAX-PX1	Cisco GSR	older documentation referred to these as -PEER

Interface Description Conventions

In the following syntax:

	[remote-device | TID | "EGM"]
	

is used to denote that one of the above is used as the first term:

	remote-device
	TID
	EGM
	

Note that [ ] are used to group options for terms while | is used to indicate options. These symbols are not used in the actual descriptions that we apply to the equipment.

General Conventions

Device names are in lower case. Campus names are in mised case or upper case as appropriate. Only certain characters are permitted: alphanmeric, /, -

Campus-Facing

 [remote-device | TID | "EGM"] [Int | 15808-Int | CID] [Campus] [DF | EGM] [ISP | DC | HPR | DC/ISP]
	

Backbone-Facing

 [remote-device | TID | "EGM"] [Int | 15808-Int | CID] [layer-3 Device] [layer-3 Int]
	

Subinterfaces

For interfaces with subinterfaces, the information is split. The layer-2 information is listed on the main interface:

 [remote-device | TID | "EGM"] [Int | 15808-Int | CID]
	

Repeat the layer-2 information, and provide the remaining information in the subinterface:

Campus:

 [remote-device | TID | "EGM"] [Int | 15808-Int | CID] [Campus] [DF | EGM] [ISP | DC | HPR | DC/ISP]
	

Backbone:

 [remote-device | TID | "EGM"] [Int | 15808-Int | CID] [layer-3 Device] [layer-3 Int]
	

Expansion of Terms

Device DNS name: short DNS name:

e.g.: lax-15540-1

TID: 15808 TID

e.g.: LAXPL03

Int: interface:

e.g.: Gi1/1/0

15808-Int: rack/subrack/slot-[TT|BT] channel:

e.g.: 1/1/2-TT56

CID: last 4 digits of the EGM circuit ID

Campus: short name of campus:

e.g.: UCLA, San Diego CC, San Diego COE

Layer-2-device: backbone router at layer 3:

e.g.: svl-dc1

Layer-3-int: interface of remote layer-3 devices:

e.g.: Po1/0

Interface descriptions are revealed in many places:

• sh ing description
• Intermapper maps
• Tools such as Cricket and Ciscoworks
• Other SNMP tools, including end-user SNMP tools

Policy

Circuit IDs are sensitive information. Therefore, CENIC does not include them in terface descriptions, as they may be unintentionally revealed if they are available in description fields.
