I have an ESW 520 8-Port switch with a management ip address of 192.168.10.2 /24 After I reboot it, I can successfully ping it from a pc with an ip of 192.168.10.123 for about 50 consecutive times.After that, I get a "Destination host unreachable" (this icmp message is sent by my pinging pc (192.168.10.123).This obviously seems like a bug.Whenever I reboot it, it goes through the same sequence.

View 3 Replies View RelatedWe 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.

I want to configure my SRW248G4 switch thru console port. Unfortunately in this switch there is no RJ45 console port input, I can only see cosole port that is look like RS232 input. I bought two standard cisco console cables that have one end with db9 and one with RJ45.
Now I have and idea to put one end of one cable (db9) to switch, and one end (db9) of second cable in my computer (COM input/output)
I need to connect two RJ45 together - this is not a problem, I know how to do this. Here is the question :I know how pinout in my computer look like but i can't find pinout of console port in my SRW248G4. There is many pictures in Internet, for many Cisco devices but this isn't working. Maybe in LINKSYS pinout look different ?
We have recently purchased SG 300-52Port Cisco Switch to support our Network but they constantly having some bizarre issues or I assume bugs, i.e. we cannot Telnet nor SSH to the switch now, whereas we were able to SSH before, we have set them up for Remote Log Services to get some syslogs and reports but no report have been generated nor logs,
I have done some testing through Wireshark and there are absolutely no reports / logs.We have some real issues with this switch and it’s hard to believe that this is a Cisco Product,

My Configuration as below
I have 8 vlan configure in SF300 (SVI with ip address)isit possible to configure dhcp server and how i can apply access-list to restrict with other vlans.
I am trying get inter vlan routing to work on a DF 300 - 24 port switch. I have an existing company network on 192.168.111.0 and want to create a vlan on 192.168.1.1 that can talk to 192.168.111.0. I have enabled layer 3 routing on the switch via console and also provided the ip routing command. I have the following VLAN's:
VLAN1 - Default 192.168.111.0
VLAN2 - 192.168.1.0
I have enabled DNS and provided my two DNS servers 192.168.111.82 & 192.168.111.212. I have set the VLAN1 interface to 192.168.111.217 and VLAN2 interface to 192.168.1.1.
Ports FE1 - FE15 are set to access ports and assigned to VLAN1 (untagged)
Ports FE16 - FE24 are set to access ports and assigned to VLAN2 (untagged)
I have set a default route for the switch to 0.0.0.0 0.0.0.0 192.168.111.254 (Draytek 2600 router). I have connected a computer (A) to VLAN1 port FE3 and a computer (B) to VLAN2 port FE16. I have set Computer A default gateway to 192.168.111.217 and its IP address to 192.168.111.94. I have set Computer B default gateway to 192.168.1.1 and IP to 192.168.1.2.
Computer A has access to Mdaemon, file server via network drives but no internet (cannot ping google) and can ping computer B and RDP onto computer B.
Computer B can ping computer A and RDP onto computer A but does not have access to the company network i.e MDaemon, file server etc. It also cannot access the internet.
From the console I can ping [URL]and all ip addresses in the company network i.e. 192.168.111.82 (DNS server). If I scan computer A wirh wireshark the internet starts working weird!

View 2 Replies View RelatedI volunteer at a school who just purchased two 48 port SGE2010 managed switches. I am not a big fan of the web gui and was hoping to see the standard Cisco command prompt instead of the menu-type interface.
Is there a way to view the MAC table showing which MAC address is plugged into which port on the switch? I have been fighting with the menu and the gui for a while now and do not see this anywhere.
When I ping an address from my windows machine, it succeeds, but when I ping to the same IP on my MAC OS X machine, it fails.
1. Why?
2. How to get successful ping on my MAC machine?
I have a 2 cisco switches that are at different sites one is a Cisco CAT4500 and other 3560. The connection between the switches is a layer 2 fibre link. CAT4500 and 3560 both have VLAN interface ip addresses in order for me to connect to the switches.
I have PC A connected to CAT4500 and PC B connecting to 3560. All these devices are the same VLAN and in the same subnet. I do have trunk links all the way though allowing this vlan as we run vlans. From PC A, I can ping CAT4500, 3560 and even PC B. This tells me everything is fine regarding Layer 2 & 3.
As soon as I move PC B and connect it to the other switch CAT4500 or move the other PC vice versa (this happens in both directions). Both switches learn that the mac address has moved locations and updates its mac address table accordingly. So when I do a show mac address table and show arp, everything has learned and moved fine. However when I try to ping any other device from PC B I cannot. So the 3560 switch PC B was originally connected to, I can no longer ping, the switch cannot see the pc also. It is as if PC B has not learned anything from the switch and cannot respond or reply to any icmp. I have tried this with different end devices, same thing. I am now thinking it has something to do with the switch.
I 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.
On the supervisor card of a cisco 6500 series, according to the following link, [URL] it only has 2 uplink ports on the card. Would I be correct in assuming that I only have those to ports that I can configure IP addresses on?
The cisco that is being devlivere is coming with a 48 port switch and 24 port fibre switch. Could I change any of those ports into a router port and configure IP addresses on those?
The supervisor card is a ws-sup-720-3b the 48 port switch is a ws-x6748-ge-tx the 24 port fibre switch is ws-x6724-sfp
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 updated the SF200 firmware from V1.1.2.0 to V1.1.2.9.44 when i was able to configure (via SF200 web interface) a port mirroring from port FE17 to FE7.But after having suppressed this port mirroring again, i was not able to reconfigure a new port mirroring from port FE1 to FE3 (the SF200 hangs).
i have also tried to return to default factory setting but this does not solve the issue.i am working on SF200-24P
I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level. I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other. I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it. This seemed to allow devices connected to the switch ports to talk to the built-in router ports. I thought this was all making sense until i applied an access-list to the router port. It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere. I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port. However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully.
It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.
