I have a Dell PowerConnect 5448 and i had a separate VLAN setup for my iSCSI traffic. Now yesterday I was going to add a few more ports to this VLAN but when i went into the switch the VLAN was gone. I know it was configured and saved because a few weeks ago when I set it up, I went into the switch several times to adjust stuff. For some reason when it lost power it may have reverted back to default settings.

I have two Cisco SG300-20 switches. Both of them are configured in L3 mode. They have several VLAN's configured.
When I reboot my switches some VLAN membership settings are lost! I have already saved the settings over and over before rebooting, and even tried to save it to the backup memory and so on. Say for example I have changed port 9 to 14 from VLAN 101 to VLAN 105. I save the configuration, reboot the switch. And then the changes are lost. This is a big problem, because servers and my iSCSI network loose connectivity. They already have the latest firmware. This issue was there three firmwares before.
This issue pop-ups when I have a power loss, or I need to reboot/shutdown them manually. It may be off-topic but I also have the feeling that the performance of the switches goes down during uptime. A reboot solves the performance issue. I don't have a performance benchmark, but I can notice it on the performance transfer rate between clients and servers.
We have a switch gc2960. It has ports configured on vlan 27 and vlan 29.It is connected to switch ch3550. It has presence of vlan 27 vlan 29 and also vlan 18 and several other vlans.Our internet firewall is connected to ch3550. It is a fortinet product, so this is not indicated on the diagram.
When the two switches were connected on vlan 29 access ports, pc's on vlan 29 on gc2960 worked as expected. vlan 27 clients of course did not work.When we switched the connecting ports to trunk ports, some weird stuff happened. Clients on gc2960 on vlan 29 could ping and resolve dns, but not browse the intenet. The same was true for clients on gc2960 vlan 27. We verified that packets from the web were coming in through the firewall. What we were thinking, is that they somehow were not being tagged to vlan 29 even though we were trunking.
When we set native vlan 29 on the trunk, then clients on gc2960 vlan 29 operated as expected. However, clients on gc2960 vlan 27 are still having this problem, we can ping and resolve dns but not browse.Consider the other switch ch2960-jstreet which has presence of vlan 18 and vlan 27. It is also connected on trunk to ch3550. We are not using native vlan on this trunk, and traffic works as expected.Is the lack of presence of vlan 18 a factor as to why gc2960 is not receiving the tagged packets correctly? Should the interface vlan18 on gc2960 have an ip address on the vlan 18 network?
We recently had redundant sup cards installed in 2 of our 4507 units after the upgrade I can no longer change Vlan's with the CNA program.I upgrade to the newest version of CNA but that didnt work.
I can still get Vlan information from my 4503's and 4506's with no problem. I figure it is an issue with CNA selecting the sup card to get it's information from?
We are in the middle of some major user moves and changes so I have had 2 of my guys working to move printers on to their own Vlan and some other changes neither is well versed in command line so I set them up with CNA for simple Vlan changes. Now with this out I have to go in and make the changes myself and keeping up with that and my other duties is getting tough.
We have 2 6513 switches with SUP720/PFC3A and various POE modules and a 6748-GE-TX facing our servers. Additionally, we have a 4Gbps portchannel trunk interconnecting the switches. We have approximately 300 Nortel IP 1140e phones in use between the two switches.For the purpose of call recording, we've attempted to mirror the voice vlan using various approaches and have been met with limited success. We mirrored the VLAN using tx, rx, and both. When using both we appear to get duplicate packets at the destination interface.We seem to lose packets completely going in one direction or another for a given call. Packets are lost before they get to the destination interface?

View 2 Replies View RelatedI managed on my own to figure out how to Telnet in, activate the web control panel, and then access that via the web. Now here is what I am trying to do, it is not that complicated. We have a FIOS connection with 5 IPS: FIOS comes in as Ethernet, without DHCP.
What I want to Assign to Ports on the Switch:
1) Uplink to FIOS
2) VOIP PBX
3) Point of Sale System
4) Internal Network
5) Public Wifi
6-8: Not in use
Each of the above 2-5 will have a router connected to the switch port, each is a separate segregated network, with its Own public IP.
I want to configure the switch to prioritize traffic in the following manner:
Port 2: VOIP: Always gets TOP priority, then Port 3: PoS (but not that important), then port 4: internal (less important), then port 5: public wifi (least important).
I recently purchased a used 2716, and I just can't seem to access the web interface.i have a Cat5e cable running from my router to Port 1 of the switch. I have my laptop connected to Port 16 via a Cat6 cable.
I have internet access both on managed and unmanaged modes, so that's working just fine. I can't seem to access the web interface however. I've tried both IE9 and FF4.
I followed the instructions to hold down the "Managed Mode" button for 30 seconds, and then wait for the switch to reboot. I've done this a few times just to be sure. This should reset it, but when I try to access 192.168.2.1, it just tells me it cannot access this page.
I need to compare a cisco ws-c2960s-24TS-s with a PowerConnect 6224, the scenario is to interconnect SAN ISCSI to 1G in RJ45.
View 1 Replies View RelatedI just purchased a SG300-10 switch and loaded the newest 1.27 firmware on it. Setup my VLANS and trunks but I have this weird issue. My setup:
I have the SG300-10 as my main switch and changed it over to L3 so it can be my main core in my small network. On port 1, vlan 200 is setup as my native PVID untagged and I have it set to trunk vlan's 210(LAN network), 220 (management vlan) tagged over to a Dell powerconnect 5224 24port switch. On port 1 of the Dell switch, I have it setup as a trunk there as well with the same setup (native PVID vlan set to 200 untagged, trunking 210 and 220 tagged).
I have no previous Cisco switch experience. I just received a brand new SG200-08 switch. It replaces a small blue Trendnet 5 port switch. I configured the SG200-08 with a static IP address which is on the same subnet as all our wired devices, then I installed it and connected a computer and printer and another switch to it. The other switch is a Dell PowerConnect 2716. I suddenly have no network connectivity with the router any longer. When I plug the network cable that runs from the PowerConnect 2716 into the SG200-08, the link status light will not go on for that port. I am going to be replacing the Dell PowerConnect with a Cisco switch as well, the SG300-10.
View 6 Replies View RelatedI have a RV082 router that is currently in prod. I have a Dell Powerconnect 5424 switch that I'd like to use in place of the unmanaged switches I am currently using.
I have the switch configured with it's IP, subnet, gateway, etc. I can plug devices into it and communicate with no problems. However, when I attempt to plug in the router, nothign will communicate to or from the switch. The devices I plugged in will not talk to each outer, ping the switch, or the router. Also cannot ping to the switch from a device plugged into the router. If I unplug the router, comm opens back up.

We are trying to config vlan 10 for data and vlan 20 for voice on the same port - port 1 of swtich SF300-24P to run both data and voice on different vlans.Do I have to add vlan 10 as an untagged vlan to port 1 and add vlan 20 as an tagged vlan to port 1?If I do not want to assign the native vlan 1 to port 1, how can I remove it ? The GUI page - assign VLAN to port does not allow to remove it.Aslo, what mode shall I set up on port 1? General, trunk or access ?

View 3 Replies View RelatedI have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)

I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
We have 6509 VSS with FWSM Module and we have created two context on it, one is INTERNALL CONTEXT othe is EXTERNALL Context? We have spanned various VLANS in switches and FWSM context level. All VLAN Gateways are configured in context level.
Activity description : We had planned migration of these devices into a new Datacenter, it was a planned activity. During migration of devices from one Dc to a new DC we broke the VSS and kept the primary running and removed the secondary switch and migrated this secondary to new DC and powered this device ON in the new DC and checked all the config was very much fine but this device was OFF network as secondary was brought to new DC just to limit the downtime during the primary switch movement.
During the activity ( Primary switch movement )We powered off the Primary switch and mean time before shifting into new Data center We had brought up secondary switch which was already existing in the DC was put live in the network and it was working fine without any issues.
Later we had moved Primary into new data center and tried to put into VSS with the secondary , during this period the secondary device into went into RECOVERY MODE and primary device was not responding and devices went off network and immediatly we removed the VSL link and brought up primary into production network without secondary online in the network ( Without VSS just stand alone switch ) network started working, but bringing up the primary we found that some of the VLANS in the FWSM was deleted and some VLAN had misconfiguration ( example : say original VLAN ip 10.200.112.1 has become 10.300.13.1 ) also some of the access list as well as SVI was deleted making configuration mismatch.
Wanted to know while syncronization b/n primary and secondary switch in VSS if we pull out VSL link would create this type of issues.
I have set up 2 DHCP pools and 2 VLANs (1 *the native* for data / 1 VLAN for voice). When I use the command "switchport voice vlan 20" the port disapear from the show vlan brief list. When I use the "switchport access vlan 20" it shows up in the show vlan brief in the correct VLAN and gives the phone an IP. I assume that using the access instead of the voice is wrong and the phones would not configure correctly. But when I use the access the phone goes to the next step and tells me the TFTP files are not found. Why does the port disapear from the VLAN list?

I am trying to setup a L2tpv3 VLAN-to-VLAN tunnel.My setup has two Cisco 890 router with Cisco IOS Software version 15.0(1) M4. These routers are connected directly on FastEthernet port 8.
One linux machine is connected on FastEthernet port 0 on each router. The two linux machines are on same vlan. I am trying to establish a vlan-to-vlan tunnel between the routers and send traffic between the linux machines.
I followed the case study 11.4 from [URL] and configured the l2tp-class and pseudowire-class. However, the vlan interface configuration is different on 890 router.
I configured a vlan interface as follows.
(config)#vlan 200
(config)# interface FastEthernet 0
#shutdown
#switchport access vlan 200
(config)# interface vlan 200
I don't see the 'xconnect' command in this context. What's wrong with my configuration?
We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
Here are the Layer 3 Design:
Client -> vlan 2 - Switch - vlan 7 -> vlan 1 - ASA 5505 -> ISP
The Layer 2 Design:
Client -> Gig2/0/13 - Switch - Gig4/0/43 -> Eth0/1 ASA5505 -> ISP
IP Address:
Client: 172.16.2.10Vlan2: 172.16.2.1Vlan7: 172.16.7.1ASA: 172.16.7.2
I assuming the switch has a problem with routing ?It is a stacked Switch with following members:
switch 1 provision ws-c3750g-12sswitch 2 provision ws-c3750g-24tsswitch 3 provision ws-c3750g-24tsswitch 4 provision ws-c3750x-48
And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.
Here are the relevant config:

i'm going mad on following problem. I'm trying to get 2 networks seeing each other while one of the network is a non VLAN network and the other one is a VLAN network.They should use the same interface so i added VLAN e0/0.122 to the interface e0/0.Send a ping from my asa to both gw-IP's made me happy at first. In second in figured out that i cannot reach any client in the other network. For testing purpose i created an permit acl to any/any for both networks, but the packets still get dropped by the default implicit rule. (deny any/anyMaybe i'm to stupid for this
