I 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?
I am trying to configure a loop back interface like so: [URL], on the following device:
C3550 Software (C3550-IPSERVICESK9-M), Version 12.2(50)SE, RELEASE SOFTWARE (fc1on port gig0/1 which is using a 1000Base-SX adapter. This is for troubleshooting purposes and it does not appear to be a feasible option. Is there another way to accomplish in the IOS?
Is buying 2 WS-C3550-24-EMI enough for the ccnp switch 642-813 (+GNS3)???????? (real switches can be connected to GNS3 right ?)

I'm looking to sit the ICND2 exam soon and have discovered that the pair of old 2924XL switches are not going to cut the mustard for the newer vlan commands and other features.
Would a pair of WS-C3550-24-SMI switches be a sensible replacement for ICND2 and possibly up to CCNP? They are available on ebay for about £80 each.
i have a Ws-C3550-24-Emi switch and i need to upgrade its flash memory to 32Mb. I couldn't find any documents in cisco website about the memory upgrade guideline. Possible to upgrade this switch to 32Mb? If so, what's the max of memory i can upgrade? and the part number for this type of memory?
View 4 Replies View RelatedHere iis a diagram of my current lab where I am using IP SLA to automatically switch from ISP 1 to ISP 2 should the connection go down (and vice versa)
My switches are C3550 Layer 3 switches. Both ISP's do work so connectivity is not the problem.
If I shutdown the fa0/19 port on SW1 the SLA kicks in and changes my defualt route out 10.0.1.0 without a problem. And when I do a no shut it comes back to tge 192.168.10.0 netowrk just as we would expect. No problem there.
When I disconnect the ISP 1 cell phone the SLA does switch the defualt route to the 10.0.1.0 netowrk. Okay, just fine so far. Here isthe problem, when i reconnect the cell phone the SLA does not come back to the 192.168.10.0 netowrk without first having to delete the SLA and then recresting it (both switches).
We have two switches; a WS-C3550-48 and a WS-C3548-XL connected via fiber uplink ports. Both switches are on the same subnet 192.168.1.0 /24. I would like to change the subnet of the second switch, WS-C3548-XL, to be on 192.168.2.0 /24. Would it be possible to assign 192.168.2.x IP addresses to both uplink ports to achive this?
Or would I need to create a separate VLAN and assign both GigabitEthernet0/1 uplink ports to this VLAN?
I'm trying to configure my C3550 with fast ethernet port 0/48 assigned to vlan 2 in static access mode and SVI vlan 2 configured as dhcp client.
But I see command ip address dhcp is not available on interface vlan 2:
Cat3550(config-if)#ip ad
Cat3550(config-if)#ip address ?
A.B.C.D IP address
Cat3550(config-if)#ip address
Could it be a problem related to the version running on the equipment (see below the output of sh version command not sure of what EA1 stands for)? I read here [URL] that this command was introduced in version 12.1(2)T
If it is a version problem is there any possibility to download upgraded version for free?

Is there any wrong with the IOS version?
i have a strange problem in my campus network.im trying to run port security on my access switches which they are 3550 with ios c3550-ipservicesk9-mz.122-52.SE when i run the port security with Sticky option, even i put 1000 mac address for just learning on the port but when i issue the switchport port-security command every pc connected to that port loses its connection with network UNTIL i enable dhcp snooping!!! all my client are getting they ip address from DHCP server but strange thing is that how on earth i have to enable DHCP snooping to port security work properly? also when i check the configuration under the interface when dhcp snooping is not yet enabled switch doesnt add any mac address under the interface so no one can work until i enable snooping and then switch adds mac addresses under the interface configuration.is this Bug on this version of IOS?[code]

I have purchased these two switches from ebay as a test lab, I plan to connect them up via a gigastack modulecable and enable ip routing on the c3550 and vlans to talk to each other.
I'm very much a procurve person and really need to get into the cisco switching.I will want to trunklacp between the switches - whats the process is setting that up on cisco switches?
I have three switches:
primary - Cisco Catalyst 3750G-24TS-24
and two SG300-28
I need to apply uplinks as follows:
3750G-24TS-24 SFP (1) -> SG300-28 (first) mini-GBIC (1)3750G-24TS-24 SFP (2) -> SG300-28 (second) mini-GBIC (1)SG300-28 (first) mini-GBIC (2) -> SG300-28 (second) mini-GBIC (2)
I would like to know, What type of mini-GBIC and SFP and cable I should use for SX Multimode?What max speed rate I will get?
I need 10gigbit uplink for this switch. What are the other devices that i need order along with this device.And what is the diff between X2-10GB-LR= and CVR-X2-SFP.if i take CVR-X2-SFP, in future how can i upgrade from one gig to 10 gig?for current use i need 10gig support required. so what are all the other devices that i need to order.Fiber multimode and distance 15Mt only.
View 2 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 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?

The core switch is a 6506 and one of the modules is the 48port POE module. The 6506 resides in the main building and we need to interconnect two other annexes to the main building via fibre. is it possible to have just 2 sfp ports on the 48 port module or how to connect the fibre cable to the switch?
Also, if the existent network is made up of Cat5e cables would it be of anyuse to use Cat6 cables for uplink for the switches on each segment to the core switch. I feel basically the Cat5e would nullify the speed of the Cat6 or am i wrong and this would make uplink speed faster.
I am having a bit of trouble with the following scenario; I have two 2901 ISRs and a 2924XL setup in the following fashion.
2924XL--->P2P-Fiber--->2901ISR--->P2P-Fiber--->2901ISR
I need to be able to reach the LAN 192.168.1.0 from 192.168.3.0 for TS but cannot get this to work. I can ping from within the switch all around and i can ping from within the woodlawn router all around but cannot ping host to host.
This is an easy question for all the architechs and designers out there. I have a stack of 3508-XL switches and one of them failed. we have 2 spares but hese are more than 10 years old and have reaced EoL.What is the equivalent switch of a 3508-xl replacement today?

Cat5e connection to basement HP 1810G-24 switch All of these devices are connected via a single Cat5e cable that was installed when the house was built. I had to re-terminate both ends of it when I moved in because the existing terminations were done very poorly. I have no idea how or where the cable is routed, nor what the quality of this Cat5e cable is. It did pass a test using my cable tester.
This single Cat5e is connected to my main HP switch in the basement equipment rack. Both of these switches have mini-GBIC ports that can utilize SFP transceivers and fiber. I priced out 2 MGBSX1 compatible modules along with a 30M multimode fiber patch 'cable' online at under $150. Although it would require at least a couple hours of work (including digging around in the attic and crawl space and drilling some holes), but running the fiber to the basement is very doable.
My question to my far more experienced forum members is if the performance gains would be worth the effort?My server is in the basement, and despite having an Intel GB NIC in my PC I am seeing read speeds of ~23MBs and writes of ~49MBs to/from my it. My server has teamed GB NICs (802.3ad LACP Layer 2) connected to trunked (LACP) ports on my HP switch.
We are using CISCO 4507R-E switch as our core/distribution switch. Out of the 7 available slots, 3 are currently being used. Descriptions is as follows:
Slot 1: 6 Port Fiber Line Card
Slot 2: 6 Port Fiber Line Card
Slot 3: Supervisor Engine
Slot 4: Empty
Slot 5: 48 Port Copper Line Card
Slot 6: Empty
Slot 7: Empty
We want to add extra 10 Gbps fiber links (approximately 12) using slot 6 and 7.
In one location we have a HP 2510-48 port switch which we need to connect to a Cisco 3560 switch. The problem I have is that we have issues connecting fibre to the HP switch, so I have decided to attached a CAT 5 to Fibre convertor at this end and another to the cisco switch.
My question you can not connect a HP switch to a Cisco switch, is this true or do I just need to confirgure something on the ports.
