Specific Searches for Your #CCNA Lab in Feature Navigator

 In 200-301 V1 CCC No Category on Purpose, CCENT-OLD, LabGear

If you did your #CCNA home lab homework from last week’s post, you probably learned a lot… including the fact that you can get frustrated using Cisco Feature Navigator (www.cisco.com/go/fn). Searching with that tool requires some decent skills at interpreting the phrases Cisco uses to describe IOS features, or at least interpreting the available help. Today’s post walks through a bit of the interpretation that’s needed when building your own CCNA lab.

What to Look for in Feature Navigator for the ICND1 Exam (CCENT)

To use Cisco feature navigator when searching for your lab gear, you need to find specific answers to many questions. Today’s post looks at two types of questions:

What IOS features do I need for the exam I want to pass?

What phrases does Cisco Feature Navigator use for those features?

I ask myself that same question when building some of those lab web pages at Certskills.com. For those pages, I don’t research for obvious features that should be in every IOS. Instead, I focus on features that I know may or may not be in certain versions, or in certain feature sets. In other words, the features that affect your decision to not buy one router, or to buy another.

Table 1 answers both of the above questions for the ICND1 100-101 exam. That is, the table lists several IOS features that Cisco happens to include within the scope of ICND1 100-101, specifically the features for which I wondered whether they would be supported in all IOS versions and in all IOS feature sets. I’m using to search to build a new version of the Router IOS features page for CCNA at Certskills.com.

Table 1: CCENT Router IOS Features and FN Phrases

Wendell’s Shorthand Feature Navigator Phrase
ACL line numbers ACL Sequence numbering
DHCPv4 client DHCP client
DHCPv4 server DHCP server
ROAS IEEE 802.1Q VLAN Trunking
IPv4 Named ACLs IP Named Access Control List
Static ip routes ip routing* (introduced in 10.0)
IPv6 Global Unicast Addressing IPv6 (Internet Protocol Version 6)
IPv6 DHCP Relay Agent IPv6 Access Services: DHCPv6 Relay Agent
IPv6 Neighbor Discovery IPv6 Neighbor Discovery
OSPFv3 (for IPv6) IPv6 Routing: OSPF for IPv6 (OSPFv3)
IPv6 Static Routes IPv6 Routing: Static Routing
IPv6 SLAAC IPv6 Stateless Auto-configuration
NAT NAT – Network Address Translation
OSPFv2 (for IPv4) OSPF
SSH Secure Shell SSH Version 1 Integrated Client  Secure Shell SSH Version 1 Server Support

What can you do with this? If you’re thinking of purchasing a router, find out the IOS version and feature set, and start searching for these features at www.cisco.com/go/fn. The table shows the literal phrases that should speed your search.

Planning to Go for CCNA Routing and Switching? More Features!

To be honest, if you plan to get your CCENT and stop with your Cisco certifications, or at least stop there with your routing and switching certifications, then you may be better off with a simulator, like Pearson’s CCENT network simulator. (The download version, updated for the new 100-101 exam, is out now; full disclosure – I get paid a little when you buy one!) But this series assumes you want a lab with real gear, so continuing that effort…

Many people who are thinking about building a home lab have a goal in routing and switching of at least CCNA Routing and Switching, and possibly beyond, and for you, you need an IOS with more features. Table 2 lists the additional router IOS features that I happened to think may or may not be in all IOS versions and all feature sets, so they’re worthy of checking out when shopping for gear. The table also lists the Cisco Feature Navigator phrases to look for as well.

Table 2: CCNA Routing and Switch: Router IOS Features and FN Phrases

Wendell’s Shorthand Feature Navigator Phrase
HSRP HSRP – Hot Standby Router Protocol
GLBP Gateway Load Balancing Protocol (GLBP)
GRE Tunnels Generic Routing Encapsulation (GRE)
OSPFv2 (for IPv4) OSPF
EIGRP (for IPv4) Enhanced IGRP (EIGRP)
Frame Relay Frame Relay
Frame Relay Switching Frame Relay Switching
EIGRPv6 IPv6 Routing – EIGRP Support
OSPFv3 IPv6 Routing: OSPF for…
SNMP SNMP (Simple Network Management Protocol)
SNMPv3 SNMPv3 (SNMP Version 3)
NetFlow NetFlow


Want a Good Place to Play?

I’m close on finishing up my research on these exact two tables for many router models, across several IOS versions and feature sets. I’m out next week – Interop New York – but hope to have a minute to post my completed tables in 2 weeks or so. The publisher has this habit of wanting me to actually deliver chapters as well, and that keeps getting in the way… ;-0

Anyway, one sweet spot appears to be 1721’s and 2611/2612 XMs, at 12.4T. Feature navigator worked well, with few oddities, in my searches at 12.4(6)T and 12.4(9)T. (Note that 12.4(6)T is advertised as the first IOS release with support for EIGRP for IPv6.) So, if you want to play in feature navigator some more, try these combinations, with different feature sets, and see what you can find!

I really cannot thank you enough for this blog. I am new to Cisco and your blog has given me an idea what should I look for when buying the kit. Saves me from buying something which will be not of much use.

Would love your thoughts, please comment.x
