You should check the Cisco web site, but I recall that you usually need to format the pcmcia from the sup prompt, and then you can use it. As for the IOS, you can write over the existing file while the router is operational, re-state the boot, and reload/repower. Should a problem occur you...

you will need to configure the switches each with an ip address in vlan1. you could browse to the switch, but this can be a denail of service risk. i telnet to all switches from a secure and designated host. you can also use the console ports since your lan is probably all in the same closet...

If your going to trunk, use 802.1q. Both router(sub-int) and switch will support it. Newer Cisco switch IOS has dropped ISL.

Simply you can have two routed connections to the internet from the same lan - nothing special. It would be a problem if it were a layer 2 connection, but this would be a layer three connection so it will be fine. The routing protocol should assess either route and adjust the load/route...

at that level of ios i am surpised you're seeing outages. i have seen that type of problem with 2950s, although not with that version, but rather the original code which was something like a 12.0.5 level. an assoicate said that cisco works caused switch outages and he had to upgrade the switch...

in additon to the prior responses, consider verifying the gbics are SX on each end, as well as the fiber optic distance for SX shich should not exceed 880' give/take pending the quality (dB loss) of all fiber optic components. The errors are just plain high so you have an obvious problem, but...

the chain is only as strong as the weakest link. you need to know the design of your lan and wan, and the demands on it in order to really understand how you can improve throughput. generally speaking the gig addition to your server should provide some improvement.

you did not include enough info. 5000s come in various sizes ie; 2-slot, 5-slot, 9-slot. if you really need a price try google. the 5000 is a blocking switch and cisco has or is discontinueing sales, but will continue support 'at a price'. the 5005 and 5009s weigh a ton dual power supplies...

It sounds like a helper address needs to be added to the router interface which acts as the gateway for the vlan in question. the vlan which works has a helper ip address on the router which points bootp requests to the correct host ie; linux server. goodluck.

some switches have a layer 3 routing engine capability - refer to cisco.com, which could be used. You can use a third switch to physically connect two differently numbered vlans, but then you're effectively making them one vlan, which can still work depending on your need.

it could be network activity such as a flood - put an analyzer on the switch. if its all on one chassis and neighbor switches don't see the same reaction, then it could be a system problem - console on watch activity, and check the log.

Buckweet is right. You atleast need to be sure the vtp domain name is the same on each unit. passwords are not necessary. if you add/subtract switches on any regular basis i would suggest setting one switch to vtp server, and not all of the switches.

there is not enough info on your posting. based on what i've read verify configurations on both ends. there may be a trunking config mis-match.

like andy said it is easy. this is a simple copy of a 6509 production config i am using which actually etherchannels between a 6509 and 2912mfs via 100fx (gig is the same). set port channel 3/1-2 312 set port channel 312 mode on set trunk 3/1-2 on dot1q 1-1005,1025-4094 you may want to...

your note confused me. in short you uplink with any one of the 24 ports, and connect your users to the other ports. Considerations - > autonegotiation: does all wiring/jacks/panels truly support CAT5 so ports and pcs can auto-negotiate a 100 MB without incurring errors. > vlans: if the network...

your buffers may/maynot relate to the pc performance. it looks like you could have several problems. first: your wiring from your nic to the switch may not be completely CAT5 - test circuit or set both ends to 10/half-duplex and see if errors cease. the duplex may be mismatched - verify the...

When I do installs in a corporate building closet, I use a simple 19" steel or aluminum universal rack at a cost of a few hundred dollars. For a data center floor, or for lock-ups, we sometimes use Great Lakes which may cost $1800+/-.

When in doubt use plenum rated cable, per nforeman's note and reference to 'plenum'. If the cable burns the fumes are not supposed to kill you.

Your wiring to your wall jack doesn't meet spec. Even if you test it, odds are you will have to have a new line run and jacks installed appropriately. Something else to consider is distance. The run from the closet to the wall jack should not be greater than 90 meters, and from switch to...

Install patch panels and stick with the existing CAT5,E, and 6. You don't need to go Gig, and you can still set your switch ports(relating to CAT5,E) to a specific speed if necessary, ie; 10/100/1000 pending switch capability. I design and manage large corporate LAN upgrades, and only in...
