I've a 7206VXR (NPE-G1) router. I would like to purchase a PA-GE port adaptor where I've to use a GBIC connector.
1. Is it possible to have a connection between PA-GE and a 3560G switch (4 SFP ports)? If yes, what type of cables & connectors are to be used?
2. Is there any GigabitEthernet port adaptors / modules for 7206vxr where I can connect RJ45 (cat 5) or SFP modules?
I have an odd situation where I cannot get a device connected to a built in switchport with out input and crc errors. When connecting to a GLC-T sfp it works fine.Here is my test layout
Outdoor wireless AP --- 10' of cat6 cable --- Gigabit POE injector --- 10' Cat6 cable --- 3560G port 48. (input and crc errors)
When I do this there are input and crc errors on the switch port. This has been confirmed on three different switches and three different outdoor AP's. We though at first it was the injector, but when we run the same setup, but instead connect the device to port 49 with a GLC-T sfp there are no errors.
Outdoor wireless AP --- 10' of cat6 cable --- Gigabit POE injector --- 10' Cat6 cable --- 3560G port 49 (GLC-T). (No errors)
I have upgraded the 3560G to the latest ios and still it has the same problem. If I run the same setup to a 2960 there are no errors at all.
Outdoor wireless AP --- 10' of cat6 cable --- Gigabit POE injector --- 10' Cat6 cable --- 2960 port g0/1 (No errors)
I have also tried manually setting the speed on the 3560G with no success.
i facing problem with my switch cisco 3560G, when it power on only System light is green and noting happen. i check with serial cable ( Console) but noting happen no booting.
View 2 Replies View RelatedWe have a Catalyst 3560G 24 port POE switch. It's been running fine for 1+ years. A few weeks ago we enabled SPAN on it to capture packets. Today, we had a random spike in CPU on the switch. Seems hardware swithing continued to work fine, but software based processes choked and effectively took down EIGRP, HSRP, etc. We collect syslogs from the router and we saw 2 crashes/reboots. Both showed the exact same error both times, with the same hex values. I **believe** the CPU usage dropped when a tech disconneted the SPAN port and it's state changed to down, but I'm not 100% sure.Could this indicate an IOS bug (I'm hoping it's not a hardware failure)? And, how to track this down to see if this could be related to SPAN? I've disabled SPAN for now.

Configuring OSPF on a catalyst 3560G Switch to connect to our building next door by way of fiber. The other two switches in the other building are running OSPF, I am trying to connect to the other building and access a server which is on a switch running OSPF. I am trying to configure the switch here to run OSPF and be able to see the neighbor, but currently can't although I've identified the networks. Maybe I'm missing something, I've followed the instructions but something is not right.

Trunks between 3560G and 2950 are set as 100/full. show int status also shows the interface negotiation is 100/full for trunks between 3560G and 2950. The issue is I keep getting outdiscard errors in trunks between 3560G and 2950. At 2950 switches, I see Recv-errors too. I checked all the trunks traffic. They are totally not high. Only serveal mbps. Most time even lower than 1mbps.
I googled this kind of issue online. I see it could be possibly caused by high volume traffic higher than the capacity. But it appears the traffic there is not high enough to cause this kind of issue. Is there any possiblity that could cause this problem?

I have been working on some Catalyst 3750's running 12.2(55)SE6 and hit an issue with CEF load-balancing over multiple equal-cost paths. Anyway this issue is now solved but it introduced me to the command 'show platform forward' - this shows you how the forwarding of a packet would be done via hardware cef (as opposed to the command 'sho ip cef exact-route' command that only shows the software cef path). Anyway I tried the command on a 3560G running 15.0(2)SE and it crashes the switch. I tried it a couple of times and verified that the MAC & IP addresses were exactly right in the command and each time the switch crashes. I have extracted the relevant bits from the crashinfo and attached them.

I like the SG-300 switches for SMB and I'd like use them in our network. Design is quite simple just 6 SG-300 switches connected to one central switch using SFP ports (using 2 port trunks) so I need 12 SFP ports and this is my question. Could you recomend me switch with more then 12 SFP ports from Cisco for this SMB network ? I don't know all the Cisco product lines and I can't find it.
View 2 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.

I have been reading the postings on this site trying to retrieve the MAC address for the client devices (computers, printers) attached to our switches. We have approximately 500 switches and I need to map the mac address to the switch. It appears the OID information is for SNMP v2. We are restricted to using only SNMP v3. I have tried using the Cisco SNMP Object Navigator without any success.

I have a got a requirement where a 24 Port Switch should have 4 SFP's and all 4 should be used at a time, So I've chosen " WS-C2960S-24TS-L"

I work at a hospital and we have 3750X-48P switches in stacks in various locations throughout the hospital. We have noticed that when an EKG machine is plugged into one of the ports on some of these switches and the EKG machines are set manually to 100/Full, the ports are no longer usable until the switch is restarted. The switch is configured for auto. If the EKG machine is set to auto, it will work and not cause problems. The link on the interface will show up/up and there will be output packets increasing. However, there will be no inputs on the link and the port is unusable. Unfortunately, even when the device is removed, the port becomes unusable for any device. Is there any way to fix this problem without rebooting the switch?

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?

Have our public IP address space masked on /24 at our Internet Router. The router portion of 3845 connects to Internet, while the internal switch connects to my internal network and seeds it with the public address space. The switch had a port configured no switchport (L3) with an ip address with /24 (ie 67.63.145.1 /24) this connects to internal IPS/IDS then to Firewall which NATs to internal, then packet shaper, web filter etc etc etc. I need to test my ISP speed so I need to "break in" to the link between the switch and the IPS/IDS. I figured I could configure another port on the switch on the 3845 but my problem is the port to my network is routed and is masked on entire /24. I tried to configure a port on VLAN 1 and give myself an available address in the L3 address space and this did not work (figured it would not but gave it a try)
Any way to get two ports configured to use the same subnet while one is a L3 routed port and the other is just part of that layer 3 routed network?
i recently deployed cat4507e switch along with 3 nos of WS-X4748-RJ45V+E - 48 port gigabit PoE modules. I am using polycom IP560 phones.
I am facing issue of some switch ports (randomly) stops supplying power to phone at random time. So far there are about 4 incident and i have been plugging those connection to different - usused ports. I am planning to RESET the switch module during weekend and i think it might fix issues with those ports.
But what would be quick and easy way to fix this issue when the issue is faced? How/what to check on switch port interface wrt to power? If switch module is falling short of overall power requirement, is there a way to boost the power?
Is there a switch that handle its 24/48 ports at 10 Gbps with copper?.

View 9 Replies View RelatedI have to configure failover Active/Standby on my ASA 5510.I am wondering how i could do for the outside interface, i mean, actually the ASA1 outside interface is linked directly to our Internet router.So now if i have to add ASA2 connecting to that router i will need a switch between them.I have already a switch for DMZ & LAN.The thing is that i will have to allow 3 switchs ports to communicate with each others.
- 1 for ASA1--outside
- 1 for ASA2--outside
- 1 for Internet router
How could i isolate these 3 ports to make them communicate alone ? Should i use VLAN for that ?And if i use VLAN, will this require to make any change of configuration on my firewalls (ASA1 & ASA2) outside interface ?I am a bit lost with this, if i am correct i will not have to do some "vlan tagging" on the firewall itself ?
My network generally runs older routers (2600 series) with 16 port switch modules (NM-ESW-16). This has always worked great since I can configure the router and the switch ports on the fly, making changes to either as necessary. Well I am upgrading to 2811 routers, and we wanted to get gigabit ethernet ports on our switch modules. I think I made an error when I purchased a few of these switch modules: NME-16ES-1G.
The first problem, is that the switch ports don't even show up on the router config, I have to establish a session into the switch, (And I can't seem to get back to the router unless I manually switch off power and restart). I don't like this type of switch module, it's like I'm running a completely separate device, and while having a layer 3 switch is cool, It doesn't let me setup routing protocols so I don't like doing it this way. I want to go back to using a switch module that simply adds a ton of ports to my router like the NM-ESW-16. (Note: The NM-ESW-16 does actually work in the 2811 and would be perfect if it were Gigabit speed.)
The seconds problem is that the NME-16ES-1G isn't actually a Gigabit switch. It has a single gigabit port, but the 16 ports are all Fastethernet, and not gigabitethernet. So ideally, I am looking for a switch module that I can fully configure from the router interface that has 16 gigabitethernet ports, and works with a 2811. IE I want to do this. [code]
I am working on a request to clean up alot of excess cabling in one of our IDF's. I noticed that many of the connections have no lights on them and probably haven't been used in a long while.

Can you configure a Cisco 1941 to use an 8 port EHWic module and the 2 onboard GE ports in a single LAN?
I've discovered you can't have the on GE ports associated with a VLan, and I'm when I've previously researched for a solution, bridging was mentioned but I cannot seem to get it to work (or completely understand it)The reason I would like to use all 10 ports on for the LAN is becuase I have 10 devices I need to connect to the 1941?
