All, I am in the process of starting down the road of migrating off of an atm backbone using 3com corebuilder 7000 to Cisco's. The question i have is for the migration I need to connect a corebuilder 7000 to my Cisco network at speeds greater than 100 meg due to performance. Can you...

Hi all, does anyone know where to find a GIG PCMCIA card? I need to have the ability to sniff a fiber gig link. I was hoping to get some form of a PCMCIA card that would support gig speeds and possibly a cable converter/transiever to convert fiber to copper IF necessary. Any other suggestions...

Tschouten, Set the config register to 0x2101 and reset the router. This will get the router into RXBoot mode and you can read/write to the memory. If this doesn't work you may have to erase the flash first then try to upgrade it. later-

All, I am new to the netscreen world but have been working firewalls / networks for some time now. My question is: I set up a statefull inspection of all packets that go over port 80 (web). If a user tries to telnet thru port 80 that user will be blocked for a specific time. How does the...

brewer61, To have two ethernet / fast ethernet ports int the SAME network on the SAME router you MUST use bridging. config looks like this: conf t bridge 1 protocol ieee <<-- enables bridging over ethernet bridge 1 route ip <<-- allows you to route IP in the bridge bridge irb interface...

Dminute, There may be some confusion here. When a switch port is set to trunk vlans with a particular encapsulation method (ISL or Dot1q) VLAN's are tagged / inserted by that switch (on the inbound but just before it's sent outbound to the remote switch) This is how the remote end knows what...

Paulk, Depending on what your future plans are for the 512k data you could... Place a &quot;Mux&quot; in front of the router and break out 512k to the router on one port and the remaining to another port for voice equipment (pbx). the 512k data could be left as a F/R link with your standard...

TIA, IS this a 2610 or a 2610XM the reason I ask is because the older 2610 have a 10-meg (ethernet) only interface. the newer 2610XM's have a 100-meg (fast ethernet) interface. Unless you have some other method to connect to your router you will need a way to have 2 ethernet interfaces on that...

Smokey, Since you are working with a 2500 I'll suggest this. issue a control break durring the boot process> you will be sent to a prompt that looks like > or rommon 1> enter confreg 0x2101 enter i this sets the configuration register to 0x2101 and then boots the router. Note# if you set...

IPCONFIG ??? WHAT??? Ok let's break this down. What i see is this: -----------Router1---(voice)---Rotuer3---------- --LAN-- --LAN-- -----------Router2---(data)----Rotuer4---------- IF you have IP cards in your pbx I assume your are using VOIP which...

EB is correct. If you want save config to tftp server once done copy running-config tftp enter your tftp server ip address and config file name and away you go.

interface fastethernet 0.1 interface fastethernet 0.2 if you have a 10-meg interface (ethernet) you can sub-interface but only to run IPX. Unless you have the new 2600XM's.

just a suggestion for debugging access-lists. add the key work log at the end of your permit statements. That way when you try to telnet to the remote host end you should see a console message saying that you were permitted access. If you don't and your access-list logs stay empty then there is...

I would suggest looking at a cisco css11000 they are designed for that purpose.

udp port 53.

easy, on the cisco router set your logging level to what ever you want to see then, logging host x.x.x.x <<<--- your IP of your linux box.

Can you post a copy of your configs? A line protocol is a layer 3 or above problem this would point a confiuration error but I can't be 100% sure. Lee

Matt, at the end you said you are running eigrp??? is this a layer-2 trunking interface or are they in the same single vlan with IP's on both side for a sudo layer-3 connection? that will help. If it's layer-2 trunking I may have the anser for you. Also (if it's layer-2) when you notice the...

Buckweet is 100% correct. What you are wanting is a channelized T1 module. Then and only then you will be able to get to the DS0 level like you want. Then you will notice it's not sub interfaces rather :x interfaces. What i mean is... channel-group 1 timeslots 1-4 speed 64 --use DS0's 1-4 at a...

Doron, check your pc's and make sure they are set up correctly (subnet mask, and default gateway). You don't have to set any routing on the router if all you want to do is ping from host 192.168.0.x --> 192.168.3.x that is because the routes are already in your routing table as (connected)...
