Cisco Switching/Routing :: 3825 - Sfp And Fiberxon Compatibility
Feb 4, 2012
I have a Cisco 3825 router with a sfp module .(multi mode Cisco sfp ) connected to a Alcatel switch with fiberxon sfp. On a Cisco router the sfp card is been recognized and is seen when i used " show ip int brief " or show inventory commands. However the line protocol is down.
is their any compatibility issue with one side Cisco sfp and other side fiberxon sfp ? we have tested Cisco sfp -------Cisco sfp works fiberxon ----------------fiberxon works .
I have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
Below is main part of the router config:
! ip source-route ip cef ! ! multilink bundle-name authenticated ! license udi pid CISCO3825 sn FCZxxxxxxx ! vlan internal allocation policy ascending
[code].....
The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?
I have a 3825 router that I have setup with the following: [code]
Its on a trunked port to my 3750 switch. I am new to this compnay and havent changed it over to IP routing on the switch quite yet.Both Vlans are setup on the 3750 without an SVI. All hosts on VLAN 1 can ping both interfaces without issue.
If I put a host on the 172 VLAN it cannot ping anything on the router. If I put another host on the VLAN they can ping each other. If I put an SVI on switch the 172 VLAN hosts can ping the switch, but still not the router. ONce I put the SVI on the switch, it can no longer ping the router. I am giving the SVI ip 172.22.1.5/24.
I have verfied with TAC that the trunk is allowing the vlans to the router.
I have been working with TAC. They have asked me to update the code on the switch, but I think they are just punting. [code]
I have a cisco 3825 router with two GE interfaces. GE0/0 is connected to a switch through ethernet cable. I have configured the GE0/0 interface with IP address. I have also configured static route for the local network. However, now I can only ping the GE0/0's own IP from the router. Here are the running-config:
hostname Router ! boot-start-marker boot-end-marker ! !card type command needed for slot 2 enable secret 5 $1$4gxa$sykc0mcaxpCIrGc86i1ZE.
[code]...
The 10.1.52.1 is the current gateway on the 10.1.52.x LAN.
After formatting the CF, the router is able to see the flash without a problem. I copied files to the flash - still able to see the contents okay. The problem ia that if i restart the router with the new flash, i get this error:

I have 2*3825 routers configured with GLBP, but traffic is moving only with one router it only fallback on other router when the 1st router is isolated.
diagram: LAN=======>ASA(Routed mode with active-standby)======>one Cisco L2 switch========>2 *3825 Router
When trace route from LAN PC show that traffic is only taking via single router. LAN gateway is defined as ASA inside address and in ASA a default route pointed to GLBP address.
RTR1 config: ========== int g0/0 ip address 1.1.1.2 255.255.255.0 glbp 1 ip 1.1.1.1 glbp 1 preemt
RTR2 config: ========== int g0/0 ip address 1.1.1.3 255.255.255.0 glbp 1 ip 1.1.1.1 glbp 1 preemt
when the client get an ip from the DHCP works for same day and all of suddenly ip get released while user working and again it doesn't ip,if the same is assigned manually it works. [code]
Are 887VAM-W-E-K9 and 800-IL-PM2 compatible? We have got both of them but it seems that router has a 30W power source and module has a 80W power source.
I have a WS-X6748-GE-TX with the WS-F6700-CFC daughter card. Is it possible to replace the WS-F6700-CFC daughter card with a WS-F6K-DFC4-AXL to make this compatible with the SUP-2T? Or, are there differences between the CFC and DFC base modules?
We have connected a single F5 box with dual links to 2 different Cisco Catalyst switches using 802.1Q trunks. F5 is configured with RSTP mode and on Cisco Switch RPVST+ is configured.STP root bridge is hardcoded on the Cisco side. Loop Guard is globally enabled.On F5 STP link type is Auto, STP Edge port is disabled since that port is connected to the cisco switch.When we are failing over the F5 primary link to the secondary link we see 'Loop Inconsistent' on the cisco switch and things dont work after the failover.We have tried configuring the F5 as STP passthrough but that doesn't fix out the issue.I have checked out the forums and found out following recommendations
1. Configuring MSTP bw F5 and Cisco for better compatibility (Not possible from Cisco side because of a major change in large production setup)
2. Configuring VSS in Cisco switches (not possible due to hardware limitation)
3. Connecting F5 using single links to each switch (redundancy compromised)
I am wondering that on which default vlan does the F5 STP instance0 sends the STP BPDUs ? the term used on Cisco side is native vlan and others use PVIDs; that F5 default vlan should match the native vlan on cisco trunk side.
We have one 3825 router used as voice gateway. For redudancy, we want to connect it to two different switches which has STP and HSRP running. Can I create a port-channel with two Giga interfaces in 3825 and connect to two different switches? Should I configure port channel in switch with only one port in each port-channel? I know server can be connected to different switches with NIC teaming. I just want to mimic that kind of setup. I did one time for port-channel in 3825, but it was connected to a stacked 3750X. So it's different case now.
I just ran into an interesting issue. VG Cisco 3825 crashes regularly with the following message in a crashinfo.

I have a router cisco 3825, it is configured with netflow for monitoring traffic with WhatsUpGold, but I can't monitor this router I don't know what is the problem.Device: Router Cisco 3825 IOS: C3825-ADVENTERPRISEK9-M 12.4. [code]
I have a switch4500 12.2 and a router 2801 IOS 15.1 and this device work well with the WhatsUp but these devices have the same configuration.I see diferents ouputs when I use show ip flow export, this output is for a router that work well with WhatsUp. [code]
we have to upgrade to nxos 5.2(4) but i cannot find same image for epld , i only see a downlable image with version 5.2(3). Do you see any problem if we upgrade kick and system image to 5.2(4) with epld 5.2(3)?
The below nexus 5020 nx-os version and type/revision of my GLC-T is compatible with each other? I noticed also the "Transceiver calibration is invalid" when i do show int e1/8 transceiver details , what does it mean?
I've inherited a network. It looks to have been setup as 10/100 originally, using Netgear FSM726S switches with fibre connecting the switches. The fibre to copper conversion is mainly achieved with 10/100 media convertors rather than GBICs - not sure why - though there are some GBICs in use. Some of the "key" switches have been upgraded to Cisco Catalyst 2960G switches, but nothing else has been touched, so most of the network still runs at 100MB.
We are upgrading two standalone 6509E chassis to a VSS system with new VS-S720-10G-3C cards. The 6509's have WS-X6748-GE-TX card with DFC3B daughter cards (see below). The compatablity matrix (see below) states that 67xx cards are supported but it goes on to state DFC3C or DFC3CXL cards are needed. So does this mean that the existing WS-X6748-GE-TX cards have to be upgraded or will they be supported?

Currently i've a cisco ws-c4506-e edge swith loaded with cat4500e-ipbasek9-mz.122-53.SG4.bin image file. Can i use this image file on a ws-c4503-e as well?
I thought I saw a post/question in regards to "how to" configure a Broadband backup for a MPLS circuit.. What I am trying to do is use a cable/dsl/ broadband (secondary) connection as a backup to a MPLS circuit (primary). I have EIGRP and BGP configured on both the branch endpoint and the tunnel headend. The tunnel is used by the interface that connects to the secondary circuit. The branch location router is a 1841 and the "headend" tunnel router is a 3825. I am wondering about the configuration/syntax of a "weight" or static route that can be used to have data flow over the tunnel when the MPLS circuit goes down - and then switch back to the MPLS circuit when it comes back on line.

We are using 3825 Cisco router with IOS version 12.4(24)T2. The unknown protocol drops on our GigabitEthernet0/1 interface is increasing. This interface is connected to our modem. What could be causing this unknown protocol drops?
cnshaccent-gw-2#sh int GigabitEthernet0/1 GigabitEthernet0/1 is up, line protocol is up Hardware is BCM1125 Internal MAC, address is ffff.ffff.ffff (bia ffff.ffff.ffff)
I have reconfigure my Cisco 3825 for ssh after we lost the config sue to a power faliure. I have reconfigure the same way it was configured before and working properly.
when I try to access the router using Putty ssh, I get to the authentication screen but after entering uername and password (enable secrete and line password the same) i get access denied.
Below is the ssh and line configuration on the router. I have seen the pdf that has been recommended here at Netpro and have followed that document but still having problem:
We have existing stack of 3 units of WS-C3750-48TS-S ( 100 mbps ports with Gigabot uplinks). with IOS as follows, Can we add WS-C3750G-48PS-S in this same stack (this is 48 Gigabit ports)?
I am looking to see if Nexus 5596UP & Nexus 2248TP GE compatible with SFP-10G-SR? The reason is because a consultant was hired on to "design" the network layout and has decided to purchase Cisco SFP+ Copper Twinax Cables which have a 10M limit. A small handful of the Data Center racks are 10-15M away... just out of reach of the Twinax. I would prefer NOT to move the LAN row so that it is more centered in the room. Can I use the SFP-10G-SR to connect the 2 switches (5596 & 2248) together? This SFP has a 26M reach on standard 10gig fiber, the small cost increase per connection is of no concern.
I am getting conflicting info about this, and need to get confirmations.Is the older 6513 (non E) model compatible with WS-X6407-10GE blade?The switch we're getting this for have WS-SUP720-3B, 6000W power supply, and WS-C6K-13SLT-FAN2.From what I read they are compatible if entered in slot 9-13, but I also heard that 10GE modules are not compatible with the non E chassis.
