Cisco Switching/Routing :: 3560E Connecting A Fiber Between Remote And Main Site
Apr 15, 2012
We have a Site that is connected via Wireless Bridge to the Main Site, the site is on separate VLAN with Cisco 3560 switch. The main site has 6509 swith. Configuration as per attached diagram. We are connecting a fiber between the remote and the main site and adding a 3560E switch at the remote site, however we would like to keep the wireless connection as a backup in case the fiber is severed the wireless will be availble. Attached diagram shows detailed cofiguration. I would like to know what should I change to make this working. STP is enabled on all switches.

At the main site, I have 3 5508 WLCs each part of a mobility group (wlcMain-MG). In NCS, under "System/Mobility Groups" for each controller, I see each controller listed as "local" with the other Controllers listed with the group name "wlcMain-MG". None of the SSIDs are "anchored".
I have a new site with a 2500 series WLC that I would like to push out 2 SSIDs. This site contains two customers. One customer is the Main customer with the second customer leasing space.
I have the Cust2 WLAN at the remote site set to have traffic egress out of a local interface on the 2500 WLC (this traffic is then tunnelled back to their Main location via an ASA which houses the DHCP scope for that vlan). I can connect to this SSID, obtain an IP Address off the ASA and am tunnelling without issue.
For the Cust1 WLAN at the remote site, I would like to broadcast an SSID from the Main location on those same APs which are registered to the 2500. It is my understanding, that I anchor the SSID at the Main site and identically configure the SSID at the remote site. This will allow the end user to authenticate to the RADIUS server at the Main site and be placed upon the correct vlan (we are using DOT1x and dynamic vlans).
For my test, I am starting simple. I have created a test WLAN with no authentication. At the main site, on 5508 WLC3, I have created the test WLAN, and placed the interface into a low security vlan (call it VLAN-low). I have anchored this test WLAN to that controller. At the remote site, I have created the same WLAN (but placed it into the management interface for now - the VLAN-low does not exist at the remote site) and configured that WLAN to anchor back to the WLC3 at the main site. I am unable to obtain an IP address from the remote site. I have placed the remote site WLC in the wlcMain-MG as well. How close does the code need to be on the controllers - the 5508s are at 7.0.116.0 and the 2500 is at 7.0.220.0? What could I be missing?

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 need to connect 4 Floor Building with 4 Cisco 2960 - 48 ports switch each other and it needs to be through a fiber. So all PCs connected to each switch would reach the LAN/WAN from the other switch. (attached is the image here with)
I see that the 2960 has 2 SFP ports each port of each switch should connect each other or how?
My simple question is:
1. What cable / patch code I have to use = Single-mode or Multimode? ( distance for each switch will not more then 25 mts)
2. Do I have to use SFP or SFP+ module?
3. What kind of SFP/SFP+ module I have to use = Single-mode or Multimode?
4. What kind of connector should patch code have = LC / SC or ?
5. How to connect each switch with redundancy like ...each switch should be interconnected with each other or I have to choose Cisco 3750G which has more then 2 SFP ports (option#1 & opetion#2 = attached here with) =
Best practice for connecting cisco switches over fiber.

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.

connecting a Cisco 3945 Router to an Ethernet WAN Link. The service provider has provided a 100M Ethernet Single Mode Fiber handoff to the customer premises with SC Connector. The CPE configuration proposed for this setup is like this. [code]
Since the SFP has LC Connector, i suppose i need to have an SC-LC Cable for connecting the Ethernet link. Do i need anything else, apart from above?

We have a site-site and remote vpn configured in same interface in ASA 5520 ( software version 8.3 ). When Remote vpn users try to connect to computers located on the distant end of site-site VPN, their request failed. I tried No-Nat between remote vpn private IP to the remote site private IP, also stated the same in Split tunneling. I cant find even the tracert, ping also timed out.

I'm facing a problem with the Cisco 1522 AP at the remote site every day that it takes about 2 hours to join the WLC, is there any way to minimize the time that the mesh 1522 AP takes to join the WLC?

My company just assumed management of a remote entity. The network has several misconfigurations and I need to make some network modifications from my office w/o losing access or incurring lengthy outage to the clients. The network consists of 1721 router and three 2960 switches.
- I only have access to the router from the Internet. I telnet off the router to the 3 switches.
The site uses a single class C 192.168.1.0 / 24. The router is running RIPv2 even though this is the only network. The prior network person (contractor) set up separate native vlans on each switch and all the ports are defined as Native trunk and access are defined to the VLAN interface assigned to the switch. So of course the logs are flooded with Native VLAN mismatch, Each 2960 switch is a VTP server but has no VTP domain.
basic network layout:
Internet => Eth [Cisco 1721] => Fa 0 192.168.1.254 ==> [SW1]
[SW1]
interface Vlan1
no ip address
no ip route-cache!interface Vlan220ip address 192.168.1.219 255.255.255.0no ip route-cache
[code]....
!interface GigabitEthernet0/1description SW2 Gi0/1switchport access vlan 204switchport trunk native vlan 204!interface GigabitEthernet0/2switchport access vlan 204switchport trunk native vlan 204!interface Vlan1no ip addressno ip route-cache!interface Vlan204ip address 192.168.1.224 255.255.255.0no ip route-cache Normally, I would assign the current 192.168.1.254 to a subinterface to Router Fe 0/0 but with each switch having its own native VLAN I am afraid I will lose connectivity to the downstream switches -- my only access is telnet off the Cisco1721 Router.

I have a few 3560E running Ver 12.2(50)se2. Can these boxes be configured to run VRF. I see a "sho IP VRF" option, but I do not see it available when under config t. Do I need to do a IOS upgrade to be able to configure VRF?

I upgraded four 3560E, 12.2(44) to 12.2(55)SEThree 3560 works fine, the last one stops after 17-18 seconds with a solid green LED. I cant get into ROMmon, the switch doesn't boot up. its like "dead but still alive"
My TS:
1: Removed all SFPs.
2: Reset PSU and fan modules.
3: Replace PSU and fan modules.
4: Try to get into ROMmon.(pushing mode button and break seq.)
Startup LED:0-1 seconds: SYST: Amber RPS: Amber STAT: Green DUPLEX: Green SPEED: Green
1-17 seconds SYST: Blinking Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF
18 s--> (only testet up to one hour) SYST: Solid Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF
A working 3560EStartup LED information. If I compare a working switch with the faulty switch I can see about 18 seconds into bootingSYST change very fast from green to amber and continues with booting,this doesnt happened on the faulty switch (solid green 18 seconds). Pushing MODE button, doesn't get me in to ROMmon, this works for all the other switches.On a normal 3560 it takes around 40 seconds before I get in to ROMmon. With this faulty switch it stops after 18 seconds(solid green) and it doesnt respond.

We have two Cisco 3560E layer 3 switches at the core of our network. The switches are configured as an HSRP pair and the clients on our network point to the HSRP address as their default gateway. So if CORE-A dies, then CORE-B will pick up the address and the default route for the clients will continue to be available.We also need to specify a few static routes on the core switch to allow us to get to specific networks. Is there a way to do this so that the routes failover in the same way that the default gateway does?

3945 is running c3900e-universalk9-mz.SPA.151-4.M2
3560e is running c3560e-universalk9-mz.150-1.SE
I've got brand new 3945's with onboard 16-port 3560e switches. On the first power up I see that there are several new vlans added that appear to be default vlans..
vlan 2 name fst2
vlan 3 name fst3
vlan 4 name fst4
vlan 5 name fst5
vlan 6 name fst6
vlan 20 name VLAN0020
vlan 21 name VLAN0021
vlan 22 name VLAN0022
vlan 23 name VLAN0023
vlan 99 name VLAN0099
I deleted the vlan.dat and reloaded the switch but these vlans come back. What these vlans are intended for and is there a better way to get rid of them? What does "fst" stand for?

I have a cisco 3560E switch setup with LACP, when using LACP i receive alot of packet loss / output drops
When a ping from the server behind LACP:
--- google.com ping statistics ---
44 packets transmitted, 39 received, 11% packet loss, time 42990ms
what would cause this packet loss with lacp?
some output from the switch:
Port-channel12 is up, line protocol is up (connected)
Hardware is EtherChannel, address is d0d0.fd58.7390 (bia d0d0.fd58.7390)

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.

I'm trying to configure "IP PIM SPARSE-MODE" command on a vlan interface on a 3560E switch but it doesn't give me the option to do this. The only option available is ip pim passive. What would cause this ? On the same switch a physical interface is already configured with IP PIM SPARSE-MODE.

I recently upgraded a remote site of mine to IOS 15-2.SE ipbasek9 on 3 3560E series switches. On switch number 2 I have 5 VG224's running (vg224-i6k9s- m) 12.4(22)T3. After the switches reloaded the VG224's dropped their connection. After doing all basic troubleshooting I reloaded the 12.2 (58)SE2 ipbasek9 image back on to the 3560E's and the VG224's reconnected immediately after reload and all phones registered.
Is the problem a licensing issue with the 15.x IOS on the 3560's or do I need to upgrade the VG224's to IOS 15.x as well for them to connect and operate via the 3560e switch running 15-2?

I have 3560e which doesn't appear to be passing igmp traffic to the upstream router
PC1 ----------- ASA ------------ PC2--------- 3560e ----------- 3825 -------------------- WAN --------------------- Router ------------- Server
My ASA runs SMR, has an igmp forward interface outside command on the inside and has a trunk port to the 3560e (V lans 32 & 48).PC2 is a test pc on the 3560e on vlan32. 3825 is my ISPs router on vlan32.
- if i try to access the stream from PC2 it works.
- if i try to access the stream from PC1, i see the igmp join leave my ASA onto the 3560E (i've captured on the 3560e's link to the ASA).
I've also captured on the ASA and i can see the igmp packet leave the outside interface but the join doesn't reach the 3825 (i've captured on the 3560e port facing the router and there is no join being forwarded).the switch is running in layer 2, 12.2(35r)SE1.

Prior we only had 62.5u multi mode.I've got 3750x switches and new SM SFP and yellow fiber patch cables. None of my links show connected. No lights and trunk port interfaces show down/down.
Is there a special command you have to do on a port when using SM fiber? Do you think I need cross over fibers?
Also, should I be able to see a laser signal light like MM or is SM a different frequency so it's not as visible as MM?

We are receiving a large amount of output drops on 4 interfaces that connect to microwave wireless.This is playing up with our Management system. Saw a bug report but that was for 3750, not the IOS version but was a similar issue. [code] The output errors tend to happen at the same time. All ports are trunks however there are other trunks on the switch that are not having these issues. [code]
