Cisco Switching/Routing :: Recommendations For A 3508-XL Fiber Switch Replacement
May 22, 2013
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?
When you aggregate multiple fiber GBICs together on the 3508G, do you configure it as an etherchannel, or as fibre-channel? I've looked around online for hours, but can't find it mentioned anywhere.
Is it possible to obtain a replacement rackmount kit for a 2960 48 port switch? I've had a read of the manuals but can't see a part number specified. The part number suggested to me (by BT) is for the 8 port version, which is not much use.
I was checking some things on my Cisco 4500 and spot checking some of the ports. Using CNA it says it is at 10. The web browser to the switch says Full-duplex, 1000Mb/s, link type is auto, media type is 10/100/1000-TX on port 6i/18 The CNA says, so what would cause the difference?
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.
I had a strange issue yesterday when onsite installing a new access switch.Port capacity full on a two switch stack of 3750 x48 PS switches (WS-C3750- 48PS-E)- New 2960 x48 PS - WS-C2960S-48FPS-L racked, with the plan of using it just as an edge switch via SFP Stacking cable.Setup the two connecting ports with simple initial config: - switchport mode trunk- no encapsulation option on the 2960, default dot1q- dot1q set on 3750 port- no shut on both sides.Connected the SFP Stacking cable but it didnt work:- %PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi1/0/1 is not supported
This is ok as I had a backup:- Next step tried using 2 x Short Haul SFP SX GBIC's with LC - LC OFNP 50/125 fibre patch lead - no joy- Extra backup of 2 x Long Haul SFP LX GBIC's with the same fibre patch - no joy- Checked the fibre and it was not a cross over so transmit and receive going down the same side, switchedand still would not come up.- Used Fibre as a straight through and still the same.In all cases there was no indication of any life in the connection.It is pointing to a faulty fibre patch lead but I know it has worked in the past. Could it be something to do with the config or device incompatibility? Or any setting I need to activate?
I am trying to connect a SF200-48 switch via Mini-GBIC MGBLX1 fibre module to a Cisco 3750 switch with a GLC-SX-MM fibre module installed both running a 1000 Mbps. When connected together they do not enable. Are there compatibility restrictions or is it that the Mini-GBIC modules cannot be used to uplink to a LAN?
Sup720 setup, possibly upgrading to Sup32's in a few years, Right now for power supplies, I am using 2 WS-CAC-2500W ,But I have to run the supplies in combined mode to get all of the cards online.What power supply should I be looking to purchase for this chassis ?
as my Netgear FVX538v2 router recently died I would like to replace this router by an enhanceable Cisco product. I'm thinking of a Cisco 2901 model that will be connected to the cable modem of my ISP and has to support PPPoE over the WAN port. The Cisco router should provide the following physical interfaces:
+ 2 WAN ports (10/100/1000 Mbps, RJ-45) + 8 LAN ports (10/100/1000 Mbps, RJ-45) + Serial Port for terminal program access + other options the FVX538v2 does provide
Will a Cisco Router 2901 be sufficient to replace a Netgear FVX538v2 device? What modules do I have to purchase?What additional licenses (data, UC, Sec?) do I have to pay for?
Situation: Currently WS-C3750G-48TS-(S or E) switches are on stack. Now these units will soon EOL on Jan. 30, 2013 and Cisco recommends that WS-C3750X-48T-S or WS-C3750X-48T-E will be used.
The question is: Will the new SKU works together in a stack with the old ones? Will there be no changes on the type of stacking cable to be used?
we're running some HP ProCurve 2520's (24 port PoE for desktops/phones) and 2510's for our server racks. The CPU's are a bit weak from what we can tell and sometimes end up with issues on them. The specs on the EAS series look like a decent jump compared to the older HP's. However I've never worked with these ever.
My other option is to go back to Cisco. However to make it fit our budget, we have to dump gig switches for 10/100 + PoE. Which isn't really a major issue on the desktop switches. We'll naturally put gig versions on the server racks. I like our ProCurves, however they cause issues from time to time.
I've also considered going back to Adtran, however I haven't kept up with what they have to offer. I'm tempted to play it safe and go the Cisco route. We're using ASA5510's active/passive for routing/firewall (gig versions).
We have Three locations (A,B,C) across campus. Location A is Main Location, While B & C are remote locations. Distance among all locations approx. 2 miles.
I want 10G Fiber among these three locations. I am taking 4510+E with SUP 7E with Redundant SUP & 10G Fiber line card(X2 10G) at Location A.At Location B & C, i need Max. 2 Nos. of 10G uplink. i am taking 4507r+E with redundant SUP 7LE. Can i terminate 10G Fiber UPLINK from Location A in to Redundant SUP 7L-E(10G SFP+) at location B & C ??
At one time, Primary SUP 10G uplink should be active & Redundant SUP 10G uplink should be standby. When primary SUP fail, redundant SUP 10G uplink will be active. Is that Possible with this scenario?Is that possible that at same time, 10G Uplink on both SUP 7L-E be Active?
I am trying to connect a 6509 switch to a 4503-E switch using single mode dark fiber over a distance of less than half a mile. Although a routine task, it does not work..We have a care 6509 switch where we concentrate all of our dark fiber connections for our remote sites. The 6509 switch already has 30 remote sites, most of them with 4503-E switches, connected in this way therefore it is a tested scenario. For the connections we use the GLC-LH-SM SFPs on both switches. Out of these 30 sites we had a similar problem with two of them, which we solved with the use of CWDM SFPs. With the CWDMs the fiber came up right away. However, I cannot keep using this solution because it is way too expensive! I had the losses of the fiber measured end-to-end and they are negligible (>0.5 dB).
In this latest case, like I said, we could not bring the connection up between the core 6509 switch and the 4503-E switch using the GLC-LH-SM SFPs. I then replaced the 4503-E switch with a 3560 and the link came up! Then I tried using a CWDM-SFP in the 4503-E, while keeping the GLC-LH-SM SFP in the 6509 and the link came alive again! Of course we already tried replacing the fiber patch cords with no luck. [code] I find it very weird for the link to work with the 3560 or with a CWDM in the 4503 but NOT with the SFP in the 4503!
Company I work for just moved into a new location. We have two data closets which are patched as independent entities, with no Ethernet tie connection. These closets are roughly 100 feet apart.
There is a fiber connection that runs between both closets, that the previous tenant used to connect the switches. I have placed a Cisco 2960 switch in each location, and added one mini SFP gbic's to each switch. After attaching both sides, neither light up. I do a sh inter gig1/0/49 on each and shows 'down down' (not admin down).
What is the trick on getting these to communciate, do I need to configure these ports, and are they supposed to light up?
What I am trying to accomplish is to get the one closet that is completely cut off, communicating by logically stacking, or 'daisy chaining' via fiber.
I turned off the lights and popped the fiber out, and I do see a faint red light (I did not look straight into it), so I think the fiber is active.
I am working on a project to connect 2 switch stacks via 10 Gb fiber. I am told that the 3750Xs do not natively receive the 10 GB SFPs. What part numbers do i need to order to make this work? Is there any IOS image requirements?
I need to interface an ASR1002 to an ONS-14454 via multimode fiber The ASR1002 will use the 1000Base SFP-GE-S SFP module in one of the built-in Ethernet ports (in 1 of the four ports) The ONS-14454 will use 10/100/1000Base ONS-SI-GE-SX SFP in the Ethernet expansion blade.
Cisco docs indicate each module is supported in specific ASR and ONS but does not indicate interfacing between the two. If these two modules will communicate without error via multimode fiber?
I have a c3560 switch that has two gig fiber modules in it. I need to uplink fiber to one of these at 100mb. This is because this port will be rate limited to 20mb and 10 percent is the lowest you can go with the rate limiting command. Is there a 100mb fiber module i can insert in the 3560
I have an old Cisco 3500XL I am using for my home lab, but was wondering can I use the fiber ports to connect to my PC. I have to correct NIC interfaces but no link indication. I did make sure the port was no down, but sill not link.
I have a WS-X6816-10G-2T module with X2-10GB-SR modules. I will be getting a SMF hand off and the length of the termination is around 100 meters. (I will be getting another hand off for Inter-DC link for which I have X2-10GB-LR module). The question is can I connect this SMF hand off (short length) on the SR module?
I have issue with connectivity 3750G with Dlink Switch, it cannot connect to non-cisco switch with fiber , But CISCO to CISCO switch it shows connectivity. My question is that is there any configuration on Cisco 3750G switch to connect with non-cisco switch through fiber (SFP) ?
I need Know what connection is using on Cisco 2811 router.I have this interface in Cisco 2811, I need Know if this port is connected to Fiber or Copper. I think is copper with RJ45 but I see 100 base TX/FX so this make me doubt about it because TX its for copper link and FX for fiber. [code]
I'm trying to upgrade some of the netwotk in my workplace.To do this I have istalled a 24port Catalyst 3560X switch.I'm looking to link it to my exsisting network via fibre.
I spoke to a local Cisco supplyer who recomended the above switch and an Allied Telesis Media converter.
I cannot seem to get the Allied Telesis unit to connect to the cisco switch.I have proved the fibre link by connecting 2 AT Media converters over the fibre.Do I have to enable something on the Catalyst switch or is the AT Media converter not compatible with the Catalyst switch?
I am doing an small project, I have to connect 4 cisco switches SF 302-08 (1 GBIC each one) to a core switch SGE 2000 (4 GBICs). Because of cable length I have go connect all 5 switches with fiber. The fiber termination is multimode LC duplex. My confusion is on the mini GBICs. There is compatibilities issues i been reading. [code]
