So 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 RepliesI 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 RelatedI 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 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?
How do I enable ports 3 and 4 on this supervisor module? I can only get ports 1 and 2 to work by default. I have a standby Supervisor in SSO mode. I'm running IOS 15.0.2SG
View 2 Replies View RelatedWe are expanding out LAN network with more 2960 access switches. All the access switches are suppose to be connected to core switch (4507R) but i have less port on the core switch.
On the core switch we have two supervisor engines (WS-X4515 ---description : "Supervisor IV with 2 1000BaseX GBIC ports"). I can see that on each supervisor engine i have two 1 GB SFP ports available and if i calculate for two supervioser engine i will have 4 1GB ports.
But at particular time only one supervisor engine is active and other is in standby mode (redundancy mode used is SSO between two SUP engines).
Can i used all 4 SFP ports for connecting 4 uplinks to the 4 access switch?Will all the 4 SFP ports active at one time or only 2 SFP ports will be active that is for only active supervisor engine.
We've got a doubt about the uplink ports of this supervisor. I've read that you have to use the four ports in 10G mode or in 1G mode, but not use for example 1 port in 10G mode and 1 port in 1G mode:
But, you can read in another sentence: " Beginning with Cisco IOS Release 12.2(25)SG, you could simultaneously deploy the dual 10-Gigabit.Ethernet ports and the four Gigabit Ethernet SFP ports on the Catalyst 4503, Catalyst 4506, and Catalyst 4507R chassis." Is it posible deploy simultaneously both type of ports?
I've got a Cisco 877-M at home which i picked up to replace the old Linksys/Cisco WAG160N, which was having dropout issues on my line?I've got a running config going on the router which is currently quite happily handling our LAN requirements (DHCP,IGMP Proxy, Firewall,DNS), but what I want to do is have an upload link QoS policy, which makes sure everyone can be able to access the net with little hassle (Not so much worried about the Downlink QoS, our connection can burst at time to 900k/sec (Currently on a 8160/384 ADSL1 Line, RIM, 300m Cable Length verified by ISP)I'd have to get the running-config from the router when I get home, but for a Home based network, what would be required in setting up a policy for Upload, to allow the following Protocols prioritised access to the net:
HTTP (Top Priority)
IMAP (Top Priority)
POP3 (Top Priority)
Streaming Audio (Med Priority)
BT (Low Priority)
These are the main ones.
I have an SA 500 with the optional port configured as the DMZ. The LAN ports are running the 192 range and the DMZ is the 172 range.
I have seperate offices (A few hundred feet apart) that have been connected with 2 un managed switches up linked with a single wire. The 192 range stuff runs over this. I need to get the DMZ out to the second room and was asking about how to do this over the single up link and switches. (Trying not to run a second wire)
My lack of understanding had me draw up this diagram attached as a picture, to ask about. What it shows is me trying to get the DMZ through the up linked switches to the other room. I thought of using 2 routers, one on each end. I've been told this is incorrect and wont work.
Maybe a purchase of a second hardware and eliminate the switches? (up link the SA 500 to another device?) What should that device be?

View 9 Replies View RelatedI have a two Cisco 4510R each with two sup V-10GE redundant. The code on these sup modules are 12.2(31r)SG3. I need some assistance in getting this setup worked out. I have all four of the 10GE populated with appropriate optics. I setup a link from one 4510R to the other using these interfaces. From the documentation I found I had to use Tengi1/1 and Tengi2/2 as the redundant pair. I plugged the up link into these ports. The Tengi1/1 (active supervisor) links up and works fine. But when I look at the ports port Tengi2/2 it isn't showing link or active. Now port 2/1 (nothing plugged into it) is showing as active.
Now is the redundancy supposed to be 1/1 and 2/1? If so, the switch is in production, when I move the connection over from 2/2 to 2/1 will it cause a outage? The reason for this is I now have a system with a 10G port and would like to utilize one of the other 10G ports. Is that possible? Or does it have to be a lag/redundant up link to work (say to another switch)?
If I have two stackable switches one that connects to the 6509 core switch and the other switch does not, do I have to uplink the switch to the other switch so that switch has route to the core switch or because the switches are daisy chain there is not need to cable one switch to to the other switch connected to core switch?

View 3 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.

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?
