create loopback interface then assign this ip of yours ip address 10.1.1.3 255.255.255.255 not 255.255.255.0

It can't be C / E as you are trying to form a trunking here. The best answer would be D / F.

DTP stands for Dynamic Trunking Protocol and is crucial to the commands below. It is also Cisco proprietary. switchport mode access - Always forces that port to be an access port with no VLAN tagging allowed EXCEPT for the voice vlan. DTP is not used and a trunk will never be formed. switchport nonegotiate - turns off DTP and forces the interface into a trunk. switchport mode dynamic desirable - pro-active DTP negotiation will begin and if the other-side is set to trunk, desirable, or auto. The interface will become a trunk. Otherwise the port will become an access port. switchport mode dynamic auto - allows the port to negotiate DTP if the other side is set to trunk or desirable . Otherwise it will become an access port. switchport mode trunk - This interface will always be a trunk no matter what happens on the other side. It will also use DTP to negotiate a neighbouring interface that is set to dynamic desirable or dynamic auto into a trunk. In the real world - I have never seen *dynamic auto*or dynamic desirable as generally network engineers try and make layer 2 related items (such as switchport settings) stable and static. There are also security risks associated with this. An access role port is usually used for an single host or device. You must also specify which VLAN you would like it to be associated with, otherwise it will default to VLAN 1 in the Cisco world. eg) interface gig0/1 switchport mode access switchport access vlan 10 Also, if you have a VLAN for voip traffic. You can also set the voice vlan as required by adding switchport voice vlan 20 A trunk port is generally only used when you want to interconnect two switches together in order to pass multiple VLANs between the two switches. In this example, the switches will use Dot1Q tagging and allow vlans 10, 20 & 30 to be passed between the two switches. Vlan 10 however, will be passed without tagging since it is set as the native vlan. eg) Switch1# interface gig0/1 switchport encapsulation dot1q switchport mode trunk switchport trunk native vlan 10 switchport trunk allowed vlan 10,20,30 Switch2# interface gig0/1 switchport encapsulation dot1q switchport mode trunk switchport trunk native vlan 10 switchport trunk allowed vlan 10,20,30 HTH, Paul

Gratuitous ARP is a sort of "advance notification", it updates the ARP cache of other systems before they ask for it (no ARP request) or to update outdated information. When talking about gratuitous ARP, the packets are actually special ARP request packets, not ARP reply packets as one would perhaps expect. Some reasons for this are explained in RFC 5227. The gratuitous ARP packet has the following characteristics: Both source and destination IP in the packet are the IP of the host issuing the gratuitous ARP The destination MAC address is the broadcast MAC address ( ff:ff:ff:ff:ff:ff ) This means the packet will be flooded to all ports on a switch No reply is expected Gratuitous ARP is used for some reasons: Update ARP tables after a MAC address for an IP changes (failover, new NIC, etc.) Update MAC address tables on L2 devices (switches) that a MAC address is now on a different port Send gratuitous ARP when interface goes up to notify other hosts about new MAC/IP bindings in advance so that they don't have to use ARP requests to find out When a reply to a gratuitous ARP request is received you know that you have an IP address conflict in your network As for the second part of your question, HSRP, VRRP etc. use gratuitous ARP to update the MAC address tables on L2 devices (switches). Also there is the option to use the burned-in MAC address for HSRP instead of the "virtual"one. In that case the gratuitous ARP would also update the ARP tables on L3 devices/hosts. HTH, Paul

I went on reformatting the whole thing on switch:rommon and then recovered ios via xModem took bloody almost 4 hours and then as soon as I slap a config to the switch and reload it, the crypto commands are back. I can delete the trustpoint, but when I try to delete the certificate chain, it says I have to delete the trustpoint (that I just deleted). A show run will will bring up the config without the crypto information, but when I copy changes to the startup-config and reload...they are back. Ugg!

Hi Jody thanks for the reply. How come even formatting the flash or the whole thing from the switch: rommon then reloading a different iOS via xModem then as soon as I slap a config to the switch and reload it, the crypto commands are back. I can delete the trustpoint, but when I try to delete the certificate chain, it says I have to delete the trustpoint (that I just deleted). A show run will will bring up the config without the crypto information, but when I copy changes to the startup-config and reload...they are back. Ugg!

I purchased a used cisco 3750 switch. I can set it up with no issue. When I do a show run, I can see that a crypto pki trustpoint and certificate was added. I can try removing it, but it will just add itself back in after a reload. After some searches, I believe that this self-signed cert is coming from the private-config.text file. If I delete it, it will just come back after a reload. I cannot copy it to tftp either (permission denied). I wanted to back it up and see if I can edit or at least look at it. I have tried to wipe out the switch by holding down the mode button. It will clear the switch and rename the config files in flash. The crypto lines are gone until I decide to make some config changes and do a reload. The crypto lines come back and the private-config.text file comes back again. Another file also comes back in flash; the multiple-fs file. I believe that this is just to access the switch via SDM. Any suggestions? Thank you.

The bad router uses it's 128mb DRAM (built-in) whereas the router has another 128mb memory module installed in total of 256mb DRAM. I came up to the conclusion that all the front ports (FEs, CFslot, USB slot) have been damaged for some reason except for console port and the WIC slots, I already tested the two WIC slots before as they are able to connect to good router's serial WIC-T1 that's why I was asking from the very start if it is possible to boot this bad router from another good router via serial (point to point) link.
