I have a question regarding uplink ports on a switch. Specifically the SFP+ variety. Could these uplink ports be used to connect directly to a fileserver? To be more specific, would the uplink port on the HP 3800 Switches connect directly to a file server that has the SFP+ card installed?
View 6 RepliesSo the 2T comes with 2 10GE and 3 GE uplink ports. Can you use all 5, one or the other, a mix, or what? How does that work? It's not really clear from reviewing the products webpage or data sheet.
View 3 Replies View RelatedWe have a single HP 2810 switch being used for an iSCSI SAN.We want to replace it with dual higher end switches.But we've got another SAN to also setup now - Dell Equallogic PS6010E - that has 10gb iSCSI SFP+ ports.Can the 4 x SFP+ uplink ports on the Dell PowerConnect PCT5548 or the HP 3800-48G-4SFP+ switch be used for just the 10gb iSCSI, while the other 48 handle the 1gb iSCSI?We were told the uplink ports don't have buffering, making them bad ports for iSCSI traffic and only useful as uplinks to another switch.We only need 8 x 10gb ports (4 for 2 servers, and 4 for the Equallogic SAN), so if the above would work, it would probably save us $10,000 from having to buy a separate 24 port dedicated 10gb switch to handle it.

the nexus 7k or 5k can be devided into 4 virtual devices ( using vdc)and making 8 uplink ports in the 2k will allow us to use the extender for all the 4 vdc's with 2 uplinks ( for redundancy ) from each vdc
i was checking the datasheet of 500X series and got confused regarding the 10GE uplinks. how many 10GE ports can be used for uplink and which transceiver should be used for 10GE copper uplink? for example, SG500x-24 switch has 24GE ports and 4x10GE uplinks. can i use the 4x10GE ports for uplinks or only 2 ports are for uplink and the rest for stacking?

View 2 Replies View Relatedwe have just purchased a few 3750x's that we intend to add to our 3750g stacks. We've purchased the 10gb uplink modules, C3kx-nm-10gt, but when they are installed they are not appearing in the switches web gui nor can you configure them correctly. If we upgrade a 3750x to 15.0.1 they seem to work fine. All of our current 3750g's are running 12.2(58)SE2 IPBASE so we don't really want to have to upgrade them all to 15.0.1
Are we missing something or do the 10gb modules only work properly with ios 15.0.1?
I know in the past on earlier models of the supervisors that you couldn't use all eight uplink ports(4 on each supervisor) simultaneously when you have two supervisors on the chassis. Is this the same case for the 10Gb uplinks on the supervisor 7-E on the 4500 chassis? I tried doing my research but couldn't find an answer.
View 3 Replies View RelatedIm now in charge of a medium/big size network (around 1200 machines).I found some connection pattern that im not shoure if it is correct.I migth be wrong, but i think this kind of connection would cause a continue RSTP change of topology (confusing about the 'direction' of the route to take), so having some latency period (this pattern of connection can be repeated several times in the whole network).BTW, there is no special configuration in switch A for saiyng that port 50 is not being used as a uplink port.

View 19 Replies View RelatedAt our office we have a weird performance problem with the following switches and connectivity:
Internet |
SG300-24 (L3) core switch (in our server room)
|SG300-10P (L2) access swtich (in our meeting room) |
SG500-28P (L3) switch (in our meeting room)
We are building a new computer infrastructure that is connected to the the SG500-28P. As you can see above the SG500-28P in our meeting room has an uplink to the SG300-10P in the same meeting room. And again the SG300-10P has and uplink to the SG300-24 in our server room. From the server room, there is connectivity to internet. The network uses a multiple VLAN's and routeing between them. Bootom line is, the internet VLAN ID 10 is tagged to trunk ports and available on the SG500-28P. So client get connected straight into the internet based VLAN.
The performance on the SG500-28P switch itself from VLAN to VLAN is very fast. But... the uplink connection tot the internet and other VLAN's on the core switch are very and very slow! At least 10 times slower than normal. So if I plug a laptop in the SG500-28P and go from uplink to uplink, it is slow! But... when I connect the same laptop to the SG300-10P the connection with only one uplink it is fast. As if three switches is to much. I can't figure out why.
I implemented the 3560E switch, this one have two Giga bit ethernet/10-Gigabit Ethernet module slots. I used the Twin Gig Converter Modules and one SFP. All configuration was applied in the Ten Giga bit, however the interface giga bit ethernet is UP UP state and the Ten giga down down.
View 3 Replies View RelatedI have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.
View 2 Replies View RelatedI was trying to uplink a switch today on a 1500m run of SMF. I have a 6509 core switch with a 16 port GBIC module. On that end I have a WS-G5486-LX with a 3m SC to LC patch cable.On the other end I have a 3750G with a GLC-LH-SM SFP. I have checked my fiber path and it seems good, (by sight, did not have an OTDR avialable).I can't get the link up at all. Tried swapping Tx Rx at one end, Tried different transceivers. Tried different patch cables. Nothing worked. At about the mid-point of my fiber run the cable passes through another network closet with a core switch for a separate network. If I break my fiber path there and try to connect in either direction it works. The only differences are the length of the fiber run and that the core switch on the other network has a CLC-LX-SM SFP.Is it the distance? Or is there some issue connecting a GLC-LH-SM to a WS-G5486-LX?

View 2 Replies View RelatedI notice that my Cisco switches have 2 fiber GBIC ports on them each and while i have been around networking for quite some time i have never dug that much into fiber. So after some quick googlefu i learned that there is lots of different types and compatibility problems.
The 2 switches i would like to connect are a WS-C3550-12T and a WS-C3550-48-EM.From what i have read these are 1000-base-fx?
Basically what is the difference. I'm looking at a breakdown of all the components connected to my switches I noticed half of them about are listing their port all the same as GI1/0/1 (routing port?). Then the rest are all different ports FA1/0/assigned# or FA2/0/assigned# (switch ports?).which are routing or switch ports and why certain ones are under each. It doesnt seem to matter which component it is (computer or printer) because some of each are under routing or switch ports.
View 1 Replies View RelatedMy university provides one Ethernet port per student in dorm rooms. They assign IP addresses based on which port you connect to and forbid multiple computers connected to the one port using a hub or switch.DHCP leases are 24 hours long, but you can switch out 10 different devices with different MAC addresses and keep getting the same IP. How does this work? Do they just figure that if you're using a hub connecting multiple stations to the one port that they don't care if there's a conflict?

View 4 Replies View RelatedI have a 2811 router with a 9 port switch module and a four port ISDN module. The ISDN Module is our connection to the outside world. FE 0/0 and FE 0/1 are connected to separate networks and both route our the ISDN connections.We are getting a new satcom system that consists of a modem, antenna control unit (ACU), and an antenna. The ACU and the modem communicate accross Ethernet and are generally hooked to a switch. Anything computer hooked to the switch can simply use the modem IP as it's gateway and be surfing the Internet without much hassle (just need the correct DNS addresses).I'd like the networks behind FE 0/0 and FE 0/1 to be able to route out the satellite modem for their Internet connection -- when the satellite is available. Is it possible to put two switch ports in a VLAN (one for the modem and one for the ACU), give the VLAN an IP in the same subnet as the modem and ACU, and then tell the router to route traffic out the modem IP address ?

In my 3750 stack switch there are more than 10 L3 vlans currently in use.In that only one vlan for example vlan 11 (we given up link directly to the nodes connected to that ports which is in vlan 11)losing connectivity for sometime and again connectivity restored.Except Vlan 11 all other vlans are working fine. When we troubleshooted the issue some of the ip's able to ping and some not able to ping. checked the interface status of that ports (no crc and input errors) and port is in up status only.we also checked cpu utlilisation ,device uptime, all are no issues found. am sharing my sw basic config and one interface status at the time of issue.But only one port learning more than 50 Mac-Addresses dynamically.and am learning mac address violation in another port which is port security and storm control enabled on that port..Its seems to be any attack or something else????

Can a router connect to a switch to gain additional ports (to both access the internet AND to maintain an internal / home network)?IP line to house, connected to modem, connected to 4-port router, connected to 8-port switch. Now, each of six rooms in my house has one Cat-5e (RJ-45) jack whose run terminates to the switch. In some of these rooms, I need two wired devices (wireless isn't an option for the devices). Can I use the LAN port of a spare, wireless router (to also use as an access point for cell phones, etc) to plug into the jack and increase the number of ports in that room to have a functional LAN and WAN? I have read tons of info on plugging switches into routers to increase the number of ports, but not the other way around. Plus, ripping open walls to expand the network isn't feasible either. My other thought, would be to replace the switch with another (2nd) router, by connecting the 1st and 2nd routers together, and have the runs terminate to the open LAN ports of both routers --= and then expand the ports in those rooms by also using additional, spare wireless routers.
View 14 Replies View RelatedThe default Gateway and DHCP server is connected to port 1 of the switch. I have various other devices on the network plugged into other ports on the switch.I want port 1 to communicate with every port on the switch, but don't want the other ports to be able to see eachother unless I specifically allow them to. For example, port 5 should see port 1, and 7, but nothing else.Everything needs to be in the same subnet. With the older Dlink switches I am used to this feature is called "Port Segmentation" but I see no such option in this switch. I have been playing with the VLAN settings but so far I have not been able to achieve this.

View 1 Replies View RelatedI have a statck of 4 2960s switches, with POE powered access points on 2 of them. All of the access points appear to be functioning normally. For some reason, on 3 interfaces connected to access points, I get the following when issuing show interfaces status:
Gi3/0/9 connected: T 7 a-full a-1000 10/100/1000BaseTX
^
My question is regarding the "T" in the status field. I can't find any documentation on this.
I've been tasked with finding all switch ports that are configured as Trunks. We plan to use LMS 4.2 to push (via Netconfig) new interface level commands to all user (non-trunked) ports. From my experience, this poses a problem because we do not know which ports are configured as trunks -vs- user ports.
Using Netconfig is not going to be easy since there is no way to script this. It would be great if I could run a show command on a switch and then have CWSI peform a change based upon the output.In other words, we need a way to run a job based upon the output of a command.
