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.

View 9 Replies View RelatedI'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.
All of my 3750's are running 12.2.55.SE.
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
[Code]......
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 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.

View 2 Replies View RelatedI'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 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]

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.

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.
