Cisco WAN :: ME6524 - SPAN Port Mirror With VACL On MPLS LDP Link
Mar 4, 2013
We have a ME6524 running as a MPLS P router. We want to mirror a port to capture a specific traffic stream (to a probe). As the port is an MPLS LDP port will this work, will both the VACL and SPAN work with MPLS tagged packets, or does the mirror and VACL work after the labels have been removed..?
I am having some problems creating a SPAN port on my Cisco 871 (running IOS 12.4-11T). My 871 is connected to a DSL modem, and uses "IP Negotiated" to get its dynamic ip address.I want to monitor the WAN port (FastEthernet4) using SPAN, but when I type "monitor session 1 source interface FastEthernet4" into the cli, it is rejected. I can successfully use any of the other FastEthernet ports, as well as Vlan1 as a source for the SPAN session. I have tried to use Dialer0 instead of FastEthernet4, but it still doesnt work.
I am having cisco asa 5520 with internet having public ip and cisco 2911 with mpls link in my office. the mpls link is between my HO and my branchmi am putting my webserver in the branch side i want to port forward one of my publicip in my office to be forwarded to branch we, server.is it poosible on the firewall ouside the local network.
I just aquired a DGS-1224T and can't figure out how to port mirror all ports. Any utility for download? Web interface is limited on port mirror. possibly an additional utility? Manual looks much different than web interface, makes me think they have a configuration utility but I can't find a download link.
Is there any way to Mirror a CISCO C3750 Switch Port Taffic to a remote Host IP Address?I know Port Mirror (SPAN/RSPAN) can copy one Interface Packet to another Interface. But I am looking for a way to miror Switch Port Packets to a remote Host (having Public IP Address and running Wirehark). Is it possible?
I'm searching for a managed switch that allows me to not only mirror a port/ports, but also to still use the destination port for the mirrors as a link to the internet/the rest of the network. Aside from this, I still need the VLAN functionality of good switches, and ideally PoE provided, too.
I have seen the majority of the features of this in the NETGEAR GS108E (http:url...), but this doesn't provide PoE to the ports and also requires Windows to log into.Is this a feature of many switches? I can think of many snooping applications where it would be incredibly useful.
Been dealing with a strange problem for several days now. It started out with a problem that I thought was VTP related but ended up being something else. I setup a span port on a 3750 that I am connected to that was mirroring the trunk connection coming into the switch.
Never saw an VTP traffic come across the connection but doing a sh vtp status indicated the traffic was arriving and getting processed. When I found some debug commands (debug sw-lan vtp), I was also able to see the packets go between switches. Seeing this issue concerns me that there is other traffic that isnt showing up during a span session.
I know that doing a span on a switch, especially using a trunk port as a source, isnt a good idea. Since I didnt have a TAP at time, this was my only choice. I have since borrowed a NetOptics TP-CU3 tap from a good friend and was able to confirm the VTP traffic was going across the trunk connection between switches.
I'm trying to configure a mirror port on a 3750. This configuration needs to replicate data from local ports, but I need that also act as a regular access port.
With the initial configuration, SPAN port, there is no problem, all the data of the configurated ports is replicating in the configurated port. On the port configurated as mirror there is a PC connected for audio recording. When the port is not operating as SPAN there is communications without problem over the LAN. But when I configure the port as SPAN, communication is interrupted.
Here is the actual configuration:
SWITCH1-PISO7#sh monitor session 1 Session 1 --------- Type : Local Session
i have configured SPAN over cisco 2960 to monitor source port traffic but after configuration i dont able to get response from destination port as my NMS is attached on destination port so i lost its web interface.
Configuration is as under.
monitor session 1 source interface gigabitEthernet0/5 (Source Port on Vlan 100) monitor session 1 destination interface gigabitEthernet0/1 (Destination Port on Vlan 200)
I'm setting up a montitor session on a NEXUS 7K as below.we are receiving in 150M of data and 0 data going out port 9/25.but port 4/24 shows 300M to the span port?
i am running c3640-is-mz.124-21.bin on a cisco router 3640. i am trying to create a monitor session in the CLI and everytime i type the command Router(config)#monitor session 1 interface ethernet2/1 % Invalid input detected at '^' marker. Router(config)#monitor session 1 interface ethernet2/1 ^% Invalid input detected at '^' marker. i get the error invalid input ?
I read quite a few documents on configuring SPAN on a cisco switch but none of them mention any limitations or any kind of CPU load it can have on a switch. I need to configure this on one of our switches and would like to know if there are any implications related to SPAN.
In s SPAN session , normally the destination prt is used for monitoring purpose only. But could destination port be used to access the equipement or PC connected to that port , for a 2960 LAN BASE image switch .
I'm having a rather bizarre and highly annoying problem with static NAT on an ME6524. I've created a virtual router (VRF CORPNET) which has one physical L3 interface, one SVI and one Loop back.This Virtual router has the sole purpose of Na Ting our internet-addressable IP addresses to another set of addresses on our Corporate WAN.
There are two NAT rules - a single 1-1 Static NAT, and an overload NAT for everything else, which uses the Loop back address. The 1-1 Static NAT is used to NAT our VPN ASA, which is used to establish a Site-Site VPN to one of our counterparts on the Corporate WAN. This works fine most of the time, however once or twice a day, the NAT just stops working, our Site-site VPN drops, and traffic is being seen on our counterpart's firewall with source address UN-NATed (They see 200.200.200.1, when they should see 30.30.30.65). When we go onto the 6524 and do a show ip Nat translations we get the following (200.200.200.1 is our VPN ASA - 200.200.200.10 is just user traffic):
ZR-BDG1-6524#sh ip Nat translations Pro Inside global Inside local Outside local Outside global udp 30.30.30.65:500 200.200.200.1:500 30.30.40.4:500 30.30.40.4:500 udp 30.30.30.65:500 200.200.200.1:500 30.30.40.4:500 30.30.40.4:500 [code].....
As you can see, for some reason we have multiple identical PAT entries for port 500. While this is the case, traffic from our VPN ASA is crossing the box without being Na Ted. If I issue a clear ip Nat trans * then the situation is immediately resolved, and the VPN reconnects without issue.
If I monitor a trunkport on the rootbridge in both directions I get Duplicate Multicast Packets on the perticular VLAN. The first guess is, that this is worked as designed and not a IOS Bug (Platform CAT6500 SUP720 IOS 12.2(33)SXI9 ) Until know I only found an old Cisco press link from 2002 with this subject.
I have 3 locations connected with MPLS connectivity … 2 mbps , 2 mbps branches and 4 mbps and I have Cisco 1841 router ?Last few days I am facing problem that Cisco 1841 router’s Lan port suddenly stop working and connectivity get disconnected.In this stage branch offices can reach up to CISCO 1841 WAN port.
( I have changed 2 different router assuming router problem but issues remain same, Hence No hardware problem )
I have pair of 5596 switches in vPC. One host say "HOST A" is connected to the primary vPC peer and other "HOST B" on secondary vPC peer.Both are in same VLAN 10. Both hosts are vpc orphan ports as their NIC is configured in active/standby mode.I have configured span session on both vPC peers with span source as VLAN 10 in rx mode.Span destination is connected to secondary vPC peer. The issue here is that I am not able to capture the traffic originating from HOST A destined to HOST B which is traversing vPC peer-link.Same issue occurs for the traffic in reverse way and span destination on primary vPC peer. In a nutshell, any traffic which crosses vPC peer-link is not getting captured.
What could be the issue and is there any solution for it. Below mentioned is the span config and relevant interfaces. [code]
I have done a bunch of research in trying to re-use an old card/router for testing our new MPLS link. I have a 45m DS3 and was wondering if the PA-MC-T3= card will work UN-channelized. I have tried the "no channelized" command under the controller to no avail. I believe that the card only works for channelized T1's.
I have few inter-AS and Hub & Spoke MPLS L3VPNs up and running but, all of them uses plain IPv4 on the PE-to-CE connecting interfaces for switching the L3VPN customer traffic. While, this is ok to route traffic between customer sites over a ISP backbone using the VRF and MP-BGP/LDP configurations which does the MPLS forwarding in the ISP backbone, i would like to know, how to enable MPLS forwarding on the PE-CE links as well to make it MPLS right from CE1 - PE1 - P - PE2 - CE2 all the way for the VPN traffic.
This way, even the last mile access to CE devices will be an MPLS link over a Ethernet PHY so that, the traffic originating from CE1 to CE 2 will be carried on a MPLS tagged Ethernet frame instead of IPoEthernet frame.
i have 2 routers 2811 interconnected together ,1 of these router running in circuit with 2 Mbps over Internet the 2nd one use MPLS Circuit with a bandwidth of 4Mbps,how configure the routing to route over the MPLS while IPSec act as standby
Running ASA5585’s in active/standby across a local campus MPLS network. Supported design, leading practice etc. Specifically our design is that two ASA5585 are configured as active/standby through a local campus MPLS network over 10gig links through ASR9k etc. The ASA’s are providing inter-vrf routing capability only with p2p l2vpn circuits configured for each logical interface between the ASA over MPLS etc.The failover link is via a direct fibre and the state link will be through a p2p l2vpn (option for direct fibre also)Is this a supported design to begin with?
I have switch Cisco 3560 and I would like to filter multicast traffic. Short explanation. This are multicast addresses from provider on VLAN 888 :
I expect that streams from acl Streamfrom888 will be dropped and the rest of streams will be forwarded. Unfortunately traffic from all streams passs through.how to configure VACL or where in my configuration is mistake?
I need to configure on a cisco catalyst 6509 two VACL. On cisco 6509 there are already two SPAN ports configured, there are problems configuring other two VACL?
These VACLs send traffic to a Traffic Analyzer (SIEM), there are particular configurations to facilitate the operation?
Is there a way to configure a VACL capture on 3560-x, we need more than 2 SPAN sessions. Feature navigator indicates that this feature is supported but it seems like it's not implemented in the IOS yet.
I´m facing to one issue with VACL. i have a network lan with 10.40.X.X/16 . in this network i have a Production v LAN 10 with 10.40.10.X/24 and i have created one vlan103 for Guest´ user as 10.40.103.X/24
My goals is to restrict the v LAN 103 to reach or access the v LAN 10, better to restrict Guest user access to the production v LAN. So i try to put this script with VACL method, but does n´t work.
Extended IP access list Restriction-Guest 10 permit ip 10.40.103.0 0.0.0.255 any vlan access-map Guest 10 action drop match ip address Restriction-Guest vlan filter Guest vlan-list 10
After that i still able to ping or access to the v LAN 10 form v LAN 103.
