| Hey guys, I have a few questions. Can anybody help me out.. ???
1. What is the difference b/w access links and trunk links on a VLAN?
2. Is Inverse ARP and Reverse ARP the same thing?

| I believe inverse arp is for to associate DLCI (Frame Relay)with an IP address. Once it knows the LCI "Hardware address" it is then possible to use InARP to obtain the IP adress of the remote site.
RARP is used by systems that know their hardware MAC address but do not yet know their IP address. | |

Thanks.. Can anybody help me with the first one???
Also, Why do you have to re-enter the the default value for the config register after using the password recovery value "0x2142"??
Thanks.

Access link: host to switch. Trunk link: switch to switch, or switch to router. Trunk links are capable of carrying multiple VLAN traffic.

The "4" in 0x2142 instructs your router to ignore the configuration stored in NVRAM, which is something you may want to do in unusual circumstances. For normal operation you want your router to read the configuration from NVRAM when it starts up. Hence 0x2102 (the "0" instructs the router to DO read the configuration from NVRAM.) | |

Great .. clears up a lot.
Thanks.

| Regarding trunk links and access links. The simplest, most important thing to remember is that access links carry ONLY 1 vlan at a time, while trunk links carry MULTIPLE vlans at the same time. Trunk links get their name from the phone company trunk lines that are used to carry multiple conversations simultaneously.

You may want to do this if you needed to recover the password on a switch or router... |
