I have a SG-300-52 port switch configured Layer 3 with mutiple VLANs. I have run out of ports. What is the best way (or easiest) to bring up a second SG-300-52 port switch with the same VLAN configuration?
View 1 Replieswhat the intention behind adding SSH to the SG200 series switches was. Is it to allow SCP copies to and from the switch for configuration and firmware updates OR is it to allow CLI access to the switches.
I have tried to SSH to the switch using PuTTY from Windows and native SSH from Linux/Unix clients, but nothing happens.
Is there some other area of configuration to enable communcation via SSH?
We have an ASA 5505 and I need to set up port forwarding for an unusual port number which will be used for FTP on an IIS server.It's a bit complex as there are 3 VLANs: these are called ISP, Server and LAN-side VPN. We need to add a TCP port 8521 forward from the server's IP in Server WAN to ISP WAN VLAN with public IP address.

I have a 25 meg fiber optic incoming service,so there is plenty of speed and bandwith available to handle these componets.

We have a DVR security system which we would like to monitor remotely. I would like to keep the DVR separate from my secure wireless router for security reasons. My thought is to connect the DVR through a cable or wired modem into my cable modem. Do you folks think this will cause an issue with the wireless router which uses DHCP to determine the IP address?

Service port = 10.100.2.1/16
Client IP = 10.1.1.10/16
I know you cannot put a default gateway on the service port, but the documentation says you can add a static route for remote management. So I tried...
config route add 10.1.0.0 255.255.0.0 <gateway.ip>
It does not take the command and says something to the effect of. "ip address/netmask conflicts with the configured ip address of the service port"

I have two vlans on the port now (6 &9) and everything works fine, all switches communicate and end devices on the switches are also talking. There is a requirement to add a device towards the end of the chain which requires it to connect using Vlan1. Once I add Vlan1 to the port onthe 3750 I lose connectivity to all the HP switches.
View 4 Replies View RelatedI have a Cisco SG300 switch on which trunks are configured. I have a server which sits on the switch via a trunk link of four network cables (4 Gbps total)on which LACP is enabled. I'm having trouble connecting to the server using VNC from a computer on the network. It doesn't happen all the time though, it's just random.
On looking at the logs of the switch, I saw something unusual. The trunk that connects the switch to the server is constantly removing all the member ports and adding them back again after a few minutes interval. That causes the trunk link to flip on and off all the time. What could be the reason that's causing it to happen? I know it could be the network cable but I'm using brand new cables and the server also is brand new.
I need adding a vlan to the trunks bundled in port channel. I know how to add v lans to a port channel with Cisco IOS but with CAT OS.
I have 2 ports bundled to form ether channel in switch which is running CAT OS. There are already few v lans allowed in the trunk of each interface. now I need to add one more v lan.
For Example:-
v lan 135 needs to be added in addition to the existing v lans.
clear trunk1/2 1-112,115,117-134,136-4094
set trunk 1/2 on dot1q 113-114,116,135
and similarly on the 2nd interface
so if I add vlan135 to the trunk one after another will it cause any service disruption?
I am a bit confused by the output of 'show run' and 'show run switch-profile' that pertains to a port-channel interface configured in a switch-profile. My main gaol is to find out how can I add/remove the allowed vlans the port-channel (configured as trunk) carries. The setup is like this. I have 2 N5k in vPC domain and Etherner1/11 on both switches is configured as trunk vPC that connects to a core switch. When I issue ‘show run’ for the port-channel and physical interface I get the following output. [code] From above it seems the switch-profile configuration is missing the 'switchport trunk allowed vlan' in the port-channel interface. If want I to remove vlan 30 from the allowed vlan, should I go under the switch-profile mode and remove vlan 30 from the allowed list even though the switch-profile configuration seems to be missing this.
View 2 Replies View RelatedI need to tear down an existing port-channel on a 3750X running c3750e-universalk9-mz.150-1.SE3.bin. This port channel is currently down down. It has three ports in it that will be added one each to three existing port-channels, I am assuming as long as the "channel-group" command is exactly the same as it is on the three existing port-channels I should be ok just adding the new port. One point to note is that the three existing port-channels all have three ports so this will be adding the fourth port to each port-channel. I know after reading that it is a best practice for load balancing to use either 2, 4, or 8 ports for a port-channel. Also what is the command to see all ports that are in a port channel?
View 1 Replies View Relatedcurrent topology is build from 4 6500 switches connected in a ring topology. Using Port channel (2x 10Gbit) links to connect left side top and bottom 6500's (DC1), 10 G bit link to connect right side 6500's (DC2) In between a 1 G bit link is used to connect top 6500's (DC1-DC2) and the same for bottom 6500's (DC1-DC2).
Path costs are 5 and 6 so the T5/4 from bottom right is blocking. Bandwidth demands are increasing, so thinking about adding extra 1 G bit links to the existing ones and create ether channels. Path costs here are 4 and 5, so T5/4 from bottom right is still blocking, but when the bottom 2 G bit port-channel is loosing one 1 G bit link the path costs of both directions become equal. So I am worried that STP will not re converge and leave me with a congested 1 G bit link. I cannot test this setup in a lab, are there any options for STP to re-converge here?

View 7 Replies View RelatedI have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
i was able to configure (via SF200 web interface) a port mirroring from port FE17 to FE7.i have supressed this port mirroring.when i try to reconfigure a port mirroring from port FE17 to FE3. The SF200 web interface crash. the SF200 seems to reboot.

I have a Cisco Catalyst 3750X switch, and I have configured port mirroring on it. Traffic from 12 of the 1G ports will be mirrored to both 10G ports, and I have connected both 10G ports to a server that captures the traffic.
Currently, I have one of the 12 1G ports connected to another server that replays a pcap file once at maximum speed (i.e. option -t in tcpreplay). I thought that this setup means I should get twice the number of packets (and rate) from the two 10G ports. However, I noticed that although the original pcap file contains 4288 packets, the number of packets from the two 10G ports varies between 31000 to 34000 packets, which is about 7 to 8 times the original number of packets. Why am I getting more than twice the amount of traffic, and why does the output vary?
I just bought 4 units of Cisco ESW-520 24Ports switches. I did some testing and found out for PORTS 1 and 12 is in "Suspended" mode and thus not able to use.This not happened to 1 but all 4 switches. Why is this so? How to disable the ports from going into "suspended" mode automatically ? I wouldn't want the ports to be in "Suspension" mode when it goes live and thus block the desktops from having internet access.

View 1 Replies View RelatedI'm troubleshooting a LAN issue I have, and I wanted to hook up wireshark to record traffic over the course of a couple of hours for later diagnostics. I went into the web administration interface, clicked Administration > Diagnostics > Port and VLAN Mirroring, and added a port mirror from the port I wanted to watch to a port to which I had connected a laptop. I picked the Tx and Rx options, and clicked Apply.I did receive lots of traffic in wireshark, but I noticed immediately that the server on the port I had mirrored was suddenly unavailable on the network -- pings timed out. This lasted until I removed the mirror, then the server was suddenly reachable once again.Does this feature not work the way I had thought it does? What I saw looked more like a forward than what I would call a mirror. The documentation leads me to believe mirroring is intended to be used in just the way I was attempting to use it.

The issue I have is that I can have either a phone or a PC plugged into a port but not both. If I plug in both then the phone works and the PC gets an IP address (Broadcast traffic) but PC cannot browse the network.
We just purchased 8 managed switches POE to swap out our existing in preparation for our new phone system. We installed them all after configuring with static IP. Deployed... and all but two work fine. Any tips for troubleshooting why two of them do not work? There are a couple other switches in the building. Could it be that a switch "upstream" from the two non-functioning switches is causing an issue? If so, how do I find out? When we put back the two "dumb" switches all was fine.
