Useful links for CCIE R&S on the Cisco Doc CD

In this lesson, I’ll add some useful links that you might want to remember when you take the CCIE R&S exam. All navigation starts from:

Ethertype Values

Some lab tasks might ask you to filter ARP, CDP, STP and such using ethertypes. You might remember most of them after a while but if you want to look them up, some of them can be found in the wireless section:

  • Products
  • Wireless
  • Access Point
  • Cisco Aironet 350 Series
  • Configuration Guides
  • Cisco IOS Software Configuration Guide for Cisco Aironet Access Points, Cisco IOS Release 12.3(8)JA

And then, select “Protocol Filters” to get to the list. Here’s the direct link if you want to see it.

They can also be found in the Bridging and IBM Networking Command Reference, but I’m still figuring out how to get there without using the direct link.

Port and Protocol Numbers

If you don’t know a certain port or protocol number, you can find a useful list in the ASA section. Here’s how to get to it:

  • Products
  • Security
  • Firewalls
  • Adaptive Security Appliances (ASA)
  • Cisco ASA 5500 Series Next Generation Firewalls
  • Configuration Guides
  • Cisco Security Appliance Command Line Configuration Guide, Version 8.0
  • Reference
  • Addresses, Protocols, and Ports

Here you will find TCP/UDP port numbers, protocol, and ICMP numbers.

Regular Expressions

You should be familiar with regular expressions and how to use them for BGP, but just in case, you can find them here:

  • Products
  • Cisco IOS and NX-OS Software
  • Cisco IOS
  • Cisco IOS Software Release 12.4 Family
  • Cisco IOS Software Releases 12.4 Mainline
  • Configuration Guides
  • Cisco IOS Terminal Services Configuration Guide, Release 12.4
  • Appendixes
  • Regular Expressions

Here’s the direct link if you want to take a look.


If I find anything else that is interesting, I’ll add it here. If you have something to share, please leave a comment in our forum!

  1. Unfortunately those ethertype values leave out a lot of important stuff, especially within the CCIEv4 and v5 context. I will repeat a couple here for completeness.

    0x800 = IPv4
    0x86DD = IPv6
    0x8100 = 802.1Q encapsulation (including dot1q-tunneling)
    0x806 = IPv4 ARP
    0x8863 = PPPoE discovery
    0x8864 = PPPoE session
    0x8847 = MPLS unicast
    0x8848 = MPLS multicast

  2. The Cisco documentation path to the IBM Bridging version of Ethernet Type Codes is:

    Products - IOS/NX-OS - IOS - 12.2 Family - 12.2 Mainline - Release 12.2 - Cisco IOS Bridging and IBM Networking Command Reference, Volume 1 of 2, Release 12.2 (under Command References section) - Appendix - Ethernet Type Codes

    This has the IPv6 entry of 86DD, but not the 88xx ones mentioned above in Nick Russo’s comment. There is a 15.x version of this too, but it doesn’t even have the IPv6 entry - strange.

  3. And the Regular Expressions page is also available under IOS 15.3, using the same path you mentioned above (minus the Appendixes step).
