CCNA Tips

Layer 3 switches and Wireless LAN Controllers can perform frame rewrite. #Cisco #CCNA #CCNATips

EIGRP and IGRP both perform equal and unequal load balancing by default. #Cisco #CCNA #CCNATips

CHAP uses a one-way hash function based on the MD5 hashing algorithm to hash the password. #Cisco #CCNA #CCNATips

Fault tolerance (redundancy) and high speed connectivity between switches are two advantages of EtherChannels. #Cisco #CCNA #CCNATips

Will be turning off @ccna_tips for the foreseeable future shortly. It hasn't been updated in over a year and was only created as a fun little Python project. Thanks to all the 1,600+ followers for the support along the way. 😀

Unassigned Cisco switch ports remain in VLAN 1. #Cisco #CCNA #CCNATips

On-Demand routing allows CDP to carry Variable Length Subnet Masking (VLSM) information. #Cisco #CCNA #CCNATips

The three modes of DTP are: nonegotiate, desirable, auto. #Cisco #CCNA #CCNATips

Cisco Discovery Protocol (CDP) operates at Layer 2 of the OSI Model. #Cisco #CCNA #CCNATips

ip http secure-server - This command enables a secure web server on a Cisco device. #Cisco #CCNA #CCNATips

A switch will forward multicast frame to all ports except the port on which it was received. #Cisco #CCNA #CCNATips

The purpose of a switch trunk is to forward multiple VLANs between switches. #Cisco #CCNA #CCNATips

VLANs 1, 1002 - 1005 are auto-created and cannot be deleted. #Cisco #CCNA #CCNATips

VLAN pruning permits or denies VLANs across a switch trunk. #Cisco #CCNA #CCNATips

On-Demand Routing allows Cisco Discovery Protocol (CDP) to include information in its periodic update messages to neighboring devices. #Cisco #CCNA #CCNATips

EtherChannel bundles multiple physical switch links between switches into a single logical link. #Cisco #CCNA #CCNATips

When you run the command 'show ip route', the C will imply that there is a directly connected route. #Cisco #CCNA #CCNATips

The backbone area (area 0) must be configured on the area border routers (ABRs). #Cisco #CCNA #CCNATips

show vlan - This command is used to view the VLAN number, name, status and ports assigned to individual VLANs. #Cisco #CCNA #CCNATips

The command 'copy startup-config running-config' will enable a router to copy the configuration files from NVRAM to RAM. #Cisco #CCNA #CCNATips
