Re: MAC Address support for c1900 series
When you set a Network Port on the switch, it will not flood a packet with an unknown destination MAC address out all of the ports. Packets with unknown destination MAC addresses are "drained" out the network port. The only practical application where I can see using a "network port" is if the MAC addresses of all the devices attached to the switch have been statically set in the switch. In this case, the switch would know about all the devices that it has to talk to, and we can send the packet with the unknown destination MAC address out the network port, hopefully to find its way to the proper destination. The problem that you will find by using a network port is that if the MAC addresses of the other devices that are connected to the switch have not been statically set, they may appear to "dropp off the network" Network printers are a big problem because they usually generate very little traffic, so the switch doesn't learn the MAC address. If you printer is sitting on port 7, and you have defined a network port, there is a good chance that any packets that are supposed to go to the printer will actually go out the network port and never find their way to the printer. In most applications, I have found it reasonable NOT to use the network port. If you do use it, you will want to make sure that you understand why you are using it, and the limitations of using it. In the Cat 1900, I believe the setting to set a network port is in the System Menu. ""Daniel Boutet"" [EMAIL PROTECTED] wrote in message 8pdi8m$nsg$[EMAIL PROTECTED]">news:8pdi8m$nsg$[EMAIL PROTECTED]... So basically it's a "trunk link" that you set as a "network port"? Or is it just any port that are basically not use a whole lot and you do not mind having the broadcast whenever a MAC needs to be learned so that way your CAM table stays within the 1024 address range for the 1900's? Doesn't the CAM work on a FIFO base? I am still not too clear on this. Also, what is the command on the switch to tell it that it's a network port? "neal rauhauser" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... The little switches have a limited MAC address table. If you know you have a link where they're going to see more MACs than they can hold you set it to be a 'network' port and the switch doesn't learn MACs from there. This is meant for a large campus environment where you have a 19xx serving a workgroup. I've worked on some real cluster (*#$%s over the years and I've never seen a real world situation where this would be needed. I'd like to hear from anyone else if they've been in some shop of horrors where this configuration was required. Daniel Boutet wrote: I was looking at the specs and it says that it supports 1024 MAC address. My understanding is that it is what the CAM table will support at one time.

Re: 64 VLAN's in Catalyst 1900 switches??
Chuck, The following URL gives info on this. See specifically: "Table 2-6: Catalyst 1900 and Catalyst 2820 VTP Modes" The summary of this information is that it depends on the VTP mode in which the switch is operating. If the switch is a VTP server, then it can have up to 128 VLANs. If it is in transparent mode, it is still 128 VLANs. As a VTP client, it can learn up to 1005 VLANs. I think the 64 number might be from an older revision of the software. I only looked at the version 9 docs: General Documentation: http://www.cisco.com/univercd/cc/td/doc/product/lan/28201900/ VLAN Documentation: http://www.cisco.com/univercd/cc/td/doc/product/lan/28201900/1928v9x/ee_scg/ 1vlans.htm You may have to unwrap the URL's.

Re: Connecting to the console port of a Catalyst 1900
If these have been in operation for 3 years, I would guess that they are the "original" Catalyst 1900 switches. These switches used a different pinout on the console port. I don't know the pinouts, but as I recall, they are almost like a null modem cable. I think one wire connects differently than a null modem cable. The newer Catalyst 1900 switches (the "standard" and "enterprise" versions) use the same cable as most of the other cisco equipment (a rollover cable with a db-9 terminal adapter). The "original" model is not able to use this. "David Toalson" [EMAIL PROTECTED] wrote in message 86BA56511DF1D31187E800805FCA88030EC3@CHS1">news:86BA56511DF1D31187E800805FCA88030EC3@CHS1... I learned about this site in the ACRC class I took in May and have learned quite a bit from the group. Now I have a question. I have 4 Catalyst 1900's that have been running default configurations for almost 3 years. No one in our company has ever attached to them to set up IP addresses for Telnet, monitoring, etc. I have not had any success in attaching to the console port. A Cisco SE sent me "special cable and terminal clip" (Turned out to be the same that comes with every router I buy. Blue cable LDW0300 72-1259-01 and clip 74-0495-01) to handle the connection. The 1900 has a 9 pin console port. I am attaching using the clip, cable and an additional 9 pin clip (same clip on both ends) onto my laptop (the same one I use all the time to connect to the console port of my routers). I am also using Reflections software as my terminal emulator - again the same as connecting to my routers via console or telnet. Same settings 8/none/9600. I have tried changing the settings on my emulator, but no changes. I have also tried rebooting the 1900 with the connection in place. Any suggestions on how to attach to the console port?

Re: Switch question
It depends on the platform and software. The switches with which I am familliar (the Catalyst 1900/2820 series) support several ports within one VLAN. In terms of actual membership, a port can only be a member of only one VLAN on these switches. In the case of trunk ports, they can carry traffic from multiple VLANs, but the trunk port must connect to another device/interface that supports trunking.
