Re: Cisco VS Foundry Networks.. [7:36448]
Foundry makes great products! On product in particular that blows Cisco away is their ServerIron Load Balancers. Cisco made a big mistake by buying Arrowpoint, and badging them the CSS line of equipment. As far as Foundry's switches go, they are very comparable. They use a Cisco replica command set, so if you know Cisco, you can adapt to Foundry fairly easily. So all in all, Foundry is a good product, worth consideration for a lot of different applications. - Original Message - From: "Washington Rico" To: Sent: Monday, February 25, 2002 6:02 PM Subject: Cisco VS Foundry Networks..

***SWITCH CONSOLE COMMAND*** [7:56849]
Hello all, When repairing a failed flash in 6509 w/MSFC I had to use the switch console command to be able to set up the boot boot variable for the router since the flash was replaced. I do not have physical access to these boxes on a daily basis but I can reach them via a console server or SSH. Problem is that when I use the console server to get to it it goes directly to the MSFC because during the repair I used the switch console command, I want to switch the console port back to the switch Supervisor but here is what it tells me. SWITCH> (enable) switch console This command is not supported on telnet session OK, if the command is not allowed on a telnet (SSH) session then how do you switch the console port back since I can't "console" into the Supervisor? Seem crazy to be only able to switch it from the console, but the console only works for the MSFC. Thanks!!!

Cisco Telephony Questions [7:57293]
Hello, I am trying to put together a case study pertaining to Cisco Telephony, if any of you experience with this subject matter would respond I would greatly appreciate it. Thanks. 1. Does Cisco use IP Telephony? If so, how? 2. What are the major business capabilities to Cisco that are achieved by using IP Telephony? i.e. increased productivity, lower long distance costs 3. What are the advantages of using IP Telephony over traditional voice systems? i.e. shared network/phone equipment, support costs, more features (if so, what) 4. What are the disadvantages of using IP Telephony? i.e. network congestion causing latency 5. How does it perform over Frame Relay?

Re: MLS between 2 Cat5K with RSM [7:51841]
If I am not mistaken, and forgive me if I am since it has been a while since I worked with a 5k/RSM setup. I believe that you only need to incorporate the MLS IP RP stuff if you are in the "Router on a Stick" configuration meaning if you have a some 72xx or 75xx's out there doing your VLAN routing. Being that your RSM is incorporated into the switch you should do some sh mls xxx on your switch to see that MLS should be running by default, and there is no need to apply that configuration. I know for a fact this is true on the 65xx platform, but I am sure it also applies to 55xx/RSM also. 16 RP addresses would be external routers ONLY.

Re: A HUB can work in Full-duplex mode? [7:52973]

Re: Duplicate packets with same SEQ #'s... [7:53024]
The tcpdump is being run on a gig span port on the core 6509, the only vlan's the span encompasses is the Server VLAN's. The VLAN's are being spanned on both core switches, so I can see why in the intrusion database duplicates are showing up since both servers are seeing the same VLAN's. I wonder why when TCPDUMP is run on once switch it sees duplicates. Like I said, I can see why the ACID database sees two entries if both servers are set on the same spanned VLAN's, but it does explain why the duplicates are notice when tcpdump is running on only one Linux Server. The host that is running tcpdump is only using 1 gigabit NIC, so no chance of seeing the packets from another interface. I guess it isn't that big of a deal, I just want to find out why it is happening, the Security folks are a litle annoyed with getting two entries in the database every time. I will evaluate spanning-tree and what not, but it seems there is some deep rooted explanation for this. Thanks for all of your replies... keep 'em coming!

Switch MAC filter [7:54880]
Is there a way on a 6509 to filter a port from seeing a traffic from a cetain MAC when the two hosts are on the same VLAN. The problem is one host keeps broadcasting NTP updates every 40 secs and the Pix SYSLOG is contantly logging it. Since the NTP host does not go through the firewall I was wondering if I could block the MAC address all together at the port the Pix is plugged into. Thanks..
