we are using the catalyst 3550 L3 for BGP routing. For e.g. Gi 0/4 is our internal interface tha we want "switch".
We need on Gi 0/5 the same network that is on gi 0/4.
How is it possible? Make it like a 2 port mini switch. Or make a bridge of these 2 interfaces without any complicated reconfiguration needed?
I have 2 3550's connected across a wireless link. [code] However, from Switch A, I cannot reach 10.1.3.9Can this 3550 not route traffic between 2 routed ports?
View 8 Replies View RelatedI live in a condo building that uses 3 Cisco Catalyst 3550 switches connected to a Comcast router with 100 Mbps download. Currently we regulate bandwidth by providing each user with 3 Mbps download. Even if only two people are active they still only get 3 Mbps download. I would like to set it up so if two people are using they each get 50 Mbps; a sort of 'dynamic qos. Is this possible with these switches? Would we have to purchase a Cisco router in order to provide this feature?

On a router I can use IP Accounting or Netflow to see what kind of traffic is moving over an interface. Are there any tools on a 3750 switch with a routed interface which would tell you who is hogging the bandwidth on that interface?

I have my main branch router (3825) and two remote routers (2821's). They are connected through leased lines that do not touch the internet. For various security reasons I have to ensure that the traffic from the remote's are encrypted in a VPN tunnel even though it is still part of a private network.I have went ahead and created the tunnels and I can verify that they are up. I have applied the cryptomap to the correct interfaces, etc.So the question is - How do I ensure that traffic is not just being router out of the interface from the remote sites back to the branch router with or without using the VPN tunnel? I've taken down the tunnels and of course, the traffic is still being passed back and fourth.
View 1 Replies View RelatedI have a subnet (vlan 104) working great across a WAN. At site 1, Router A (3745) has the L2TPv3 tunnel configured while Router B (7204) has a routed interface on vlan 104.
The only thing router A is doing is the tunnel, so I'd like put the tunnel on Router B and eliminate Router A.
The trouble is, when I move the configs to Router B, the tunnel comes up, but the far side does not receive traffic over the tunnel.
Router B shows sending and receiving packets (per the 'sh l2tun session all' command). The far end router shows sending packets but receiving 0.
Is it a problem to have both the vlan 104's L2TPv3 xconnect interface and the vlan 104's routed inteface on the SAME router?
confirm whether the Catalyst 3550 with IOS Rel. 12.2(44)SE is compliant with POE IEEE 802.3af? I see some conflicting informaiton on Cisco's web site. Before Release 12.1(22)EA2, Catalyst 3550 PoE-capable switches (without intelligent power management support) caused high-power powered devices that supported intelligent power management to operate in low-power mode. Devices in low-power mode are not fully functional.
IEEE 802.3af—The major features of this standard are powered-device discovery, power administration, disconnect detection, and optional powered-device power classification. For more information, see the standard.

View 2 Replies View RelatedI have two 1252s on ports 1 and 2 off a Catalyst 3550. No other device on the switch except the fiber uplink.
Initially 1252 #2 (on port 2) resets for no reason at no specific time. We did not have a problem with 1252 #1.
The show ver on #2 does indicate that equipment resets due to power. I figured the 3550 is having problems powering two 1252s so had this AP on PWRINJ4 (validated its not drawing power via show power inline).
Today, #2 does not reset. However, now #1, which is the only device using inline power is now resetting. Same thing, reset due to power. Same weird behavior, at no particular time.
I've also have "no cdp enable" out off each port as i understand CDP sometime cause device to not boot up (15w versus 15.4w issue).
Both AP btw are Standalone IOS.

View 2 Replies View RelatedI can assign IP addresses to any of the 24 FastEthernet ports (it is a 24 port switch!). However, I have fitted the WS-G5482 Gigabit adaptor to give me Gig ethernet capability. It does not seem to be possible to assign an IP address to the adaptor.I realise that as it is an 'add on module' (well, a plug in module) this is different to the 24 port in the 'body' of the switch. I also have read that these Gig adaptors will only connect to other Gig adaptors (I found that out by trial and error, and then confirmed it by searching here).it's not possible to assign an IP addy to one of the plug in modules; it is not a big deal but I am planning to assign some IP addresses for remote management etc. I was going to use the Gig port for this but it may not be possible.
AH PS I am using the switch and connecting to the internet via the Gig adaptor, then out from one of the fastethernet ports to another little switch and then on to a router and out to the internet, so the switch and the plug in module are working fine.
I am attempting to create a mass upgrade server for some of our more standardized equipment since our vender cannot upgrade them pre-shipping for us, we've got to do them on our own. This means using a terribly organized wizard written in what appears to be Java...
I have an aversion to Windows and felt that I could accomplish the same thing using expect scripts and a Gentoo Linux server; now all I need is to set my Cisco 3550 (c3550-ipservicesk9-mz.122-44.SE6.bin) to have each port on it's own VLAN, except for fa0/1 which will be a trunk port to communicate with all ports as well as the server.
correlates the older IOS format naming compared with the newer? I have an older catalyst 3550 that might need an IOS upgrade due to us starting to implement dot1x. The reason that I say this is that some of the commands in the dot1x config guide, such as aaa accounting dot1x, are not valid on this platform. The current IOS is c3550-i5q3l2-mz.121-8.EA1c but the newer format is the ipbase, ipservices, etc. format. There is a newer ios but how do I convert from one to the other? I think I need to research the IOS to see if the new commands are there as well as I want to make sure there are no gotchas from a hardware standpoint if I upgrade.

I have a catalyst 3550 and will be using it to run my cisco 7940 and 7960 ip phones with POE. When I plug the phones into the switch they power up just fine but the phones will not dial out as they have little x's by the line. I have also tried going through the set up of the 3550 but get stuck in one place. When I go to the 10.0.0.0, the screen will not allow me to enter the telnet page or allow me to enter any information. In the manual it shows a pic of what the screen should look like when I go to 10.0.0.1, but I am getting an entirely different page.
What I need to do to get everything set up correctly?
I am testing on lab equipment (2 Catalyst 3550 and 1 Catalyst 3560) HSRP version 1 and 2.I successfully created a load balancing between the two Catalyst 3550 on a couple of vlans (11 and 12) on ver 1
now, just adding the command "standby xx version 2" my hosts on the 2 vlans are completely unable to ping the virtual IP def. gw on debugging i checked that msgs are exchangedthe two cat 3550 are seeing each other on HSRP (active / standby roles)the real ip addresses are pingable rebooted the swiches (just as a last resort try)deleted arp chache on hostsremoved the auth on hsrp all of this no effect.
i also tried to modify the priority on the cat 3560 (before he was on both vlans in standby) to make it the active one and with the same config it worked flawlessly.
My only idea is that there is a bug on CATs 3550 (IOS: c3550-ipservicesk9-mz.122-55.SE4.bin) [code]
I was trying to config qos on 3550 interface
Match protocol is not supported for this interface
So does this mean that qos is not supported on 3550?
Quick question here. Using 3750E series switches with multiple VLANS configured. These switches serve as our 'core'. I have SVIs configured for the different VLANs and add inbound ACLs in each of the SVIs to control traffic between VLANS. This switch also terminates a P2P Ethernet link which connects to our Colo facility. The port used for this is configured as an L3 port. I noticed today that I was able to send traffic across this L3 link that I thought should have been blocked by an ACL I had in place but it wasn't. So the traffic flowed from a port in say VLAN 20 across this L3 link (assigned with an IP address). Would this traffic flow not cause traffic to be checked against an ACL applied in the inbound direction on the SVI of VLAN 20 (int vlan 20)? Traffic does get checked when routing between SVIs. Why would it not get checked when routing between SVI and L3 interface?

While working at a client site today, I was troubleshooting some ICMP connectivity for a network we have created.I turned on 'debug ip icmp" on the 3550 switch int he middle, and was inundated with the following debug output:

This output fires several times a second, and based on how often it is firing, I am curious if it may be a culprit with respect to the fact that the client has indicated that they have some slow internet.Should the next step be to look at the workstation at 172.16.1.5?
