I have currently a Dell powerconnect 6248 switch combined with a netgear UTM router. I have a basic understanding on how things should work but I don't have the knowledge to apply it as I'm new to setting up vlan and the person before me did the basic configuration like this:
defined 5 VLAN in the netgear router
defined the same 5 VLAN in the dell 6248
connected the dell switch to the netgear router via a trunk port.
Right now all the inter vlan traffic pass thru the netgear router as the dell switch as a trunk port connected to the netgear box who then give dhcp and set himself as the default inter vlan route. I would like to stop that since I would like the cisco switch to handle all the vlan routing for both switch and those switch to send their dhcp request to my win2k8 server.
I did set the sge2010 in layer 3 mode from the small business telnet interface. I then setup the same 5 vlan in the cisco switch.
If I understand this well I need to define an IP address for each vlan interface on the cisco switch for it to be able to route things, I have set them all as x.x.x.3 (x.x1.3 vlan 1, x.x.2.3 vlan2, etc) Then I need both swtich to forward all dhcp request to my dhcp box wich is in vlan 2. My DHCP server will have 5 range of IP address to hand out. my server are connected directly to the dell switch on vlan 2. I have set up a port in the dell switch in trunk mode and did the same thing in the cisco switch and connected them togheter to send all vlan packet. The current setup doesn't work so I need to finalize that setup so that everything works.
I'm reading this definition in the cisco T-shoot student guide:
"Align-Err: this is the number of frames with alignment errors, which are frames that do not end with an even number of octets and have a bad cyclic redundancy check"
I don't understand what "frames that do not end with an even number of octets" actually means. Did they mean even number of bits? or does a frame's lenght need to be an even number for it to be considered valid?
we have a 7206vxr router with pa-pos-2oc3 and SFP-OC3-IR1-C. Our provider wants us to check transmitted and received power on the SFP.
I already looked around and know theres no way to check or adjust transmit power and saw its -15 to -8dbm on the datasheet.
Is there a way to check received power?

We have 4 data T1s providing our office with 6Mbs of internet bandwidth.I have been trying to track down the reason(s) for the steadily increasing frame and abort errors on the Multilink interface of our new router.We have a new 2961 with 2 2 port T1 interface cards (VWIC2-2MFT-T1/E1).
At first it looked like the T1s were completely clean, but after diving down a bit the last of the 4 T1s does appear to have a decent amount of slip and error seconds.Is that something that would cause the Multilink interface to show input, frame, and abort errors?Any config or debug commands I should start with to narrow down what might be causing this problem?

I have just purchased Dell PowerConnect 6224? how can i create two VLANs (vlan 10 - 192.168.10.x/24 & vlan 20 - 192.168.20.x/24) that can communicate with each other without setting servers/workstation network gateway point to the vlan ip address?
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 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.

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.

View 2 Replies View RelatedI'm trying to connect my new Dell Dimension 8400 (3.0Ghz/512Mb/XPsp1) to my home wireless network. I installed two diiferent PCI adapter cards in my one available PCI slot -- an older D-Link (11b) and a brand new Netgear (11g) (which Dell Sales assured me is compatible). Both cards detected my Netgear wireless router and provided an excellent internet connection, so I'm assuming they were seated properly. The problem is that every time I shut down the system I get the blue screen of death with the following message:
-Hardware Malfunction
-NMI: Parity Check/Memory Parity Error
-The System has halted
The system runs and shuts down perfectly when the PCI cards are removed. D-Link and Netgear Support technicians told me I have to contact Dell, but Dell Support doesn't seem to have an answer for me. Which wireless PCI adapter cards are truly compatible with Dell hardware?
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've no experience in VoIP and been ditched with looking at an IP trunking problem on our network.The users where getting dead lines or silent calls, but it seems after re-seating IP trunking card here and there around the network a few times, all is settled to normal. Unfortunately it's a third party that look after the majority of the telephony, and as they can't figure out why this happens they often say it must be a problem with the data WAN it traverses.So I started trying to figure something out, I have IPSLA monitoring setup in Solarwinds on most of the routers and all looks well from that aspect; MOS is 4.34 and Jitter is only 1ms at worst. I've taken a wireshark packet capture of the IP trunk by mirroring the port on the switch at a main site where I've been told a lot of calls are routed through. Inside wireshark I used the 'telephony> voip calls' tool and decoded all the calls. The output is showing most calls have 'Out of Seq' and 'Wrong Timestamp' at around 25-50%. Although these calls seem fine otherwise, and I took this capture whilst the fault was not occurring. I know I need to capture next time when the fault is occurring, but this is what I have for now.How can i fix this or even start to troubleshoot further?
p.s- each site has two routers running GLBP to the WAN, over two ISP locations. I read something about having consistent routing to avoid packets arriving out of sequence, but haven't found anything yet to say this is how I can/should do that.

I just installed a new ACS 5.1 to authenticate wireless PEAP users, so I created an Access policy "WirelessUsers" with identity store being Windows Active directory and all domain users are selected, and create a service rule that dictates that if the authentication protocol is radius, network device belongs to WLC device group, the result service will be "WirelessUsers", so this part worked perfectely, all domain users are able to gain wireless access via their DOMAIN/usernames and domain passwords. Now I want ACS local indentity store users (those local usernames can be the same or different from their AD usernames) to be able to manage those controllers, so I created another access policy "DeviceAdminUsers" with identity store being local users, another service rule which says that if the authentication protocol is radius, network device belongs to WLC device group, the result service will be "DeviceAdminUsers". The problem is that with the setup, whenenve when I try to SSH to WLC, ACS always put me in "WirelessUsers" access policy, even the login name does not have DOMAIN pre-pended or the login name simly does not exist in AD. if I put the second rule in front of first rule, I am able to authenticate with ACS local username/password and gain access to WLC, but wireless users will fail to authenticate, because ACS is trying to put regular wiress users in "DeviceAdminUsers" access policy. I would expect if username does not exist in AD, ACS should proceed with next rule. Similar requirement was easily achieved in ACS 3.3.
