I think the additional port mirror should look something like the lines below, but I cannot figure out how to add a session: console (config)#monitor session 2 source interface 1/g12 A source port cannot be a destination port. The monitoring of traffic received on port 1 is disabled, but traffic sent from this port continues to be monitored. For example, "100,200,205,305" or "100-300". For interface-id, specify the source port to monitor. I have looked through the config guides, and all they show is how to add ports, but they don't show how to remove ports from a SPAN session. monitor session 1 destination interface gigabit-ethernet 0/23 monitor session 1 source interface gigabit-ethernet 0/9 rx Is either port 0/9 or 0/23 a trunk port with VLAN tagging, because that may cause an issue if the device at the mirroring destination doesn't support VLAN tags. Monitor session 1 source interface fa05 monitor School University of Illinois, Chicago Course Title CIS CIS Type Lab Report Uploaded By redeyez Pages 42 Ratings 97% (33) This preview shows page 38 - 42 out of 42 pages. To create a SPAN source session to monitor the traffic that is bridged into a source VLAN, use the monitor session session_number source vlan vlan-id command. Switch (config)#monitor session 1 source interface fa0/1 Switch (config)#monitor session 1 destination interface fa0/2 You can verify the configuration like this: Switch#show monitor session 1 Session 1 --------- Type : Local Session Source Ports : Both : Fa0/1 Destination Ports : Fa0/2 Encapsulation : Native Ingress : Disabled range. . S1# telnet 192.168.1.1 Trying 192.168.1.1 . Or Device(config)# monitor session 1 source interface fastethernet 1/0/1: Specifies the SPAN session and the source port (monitored port). monitor session 1 destination interface gigabitethernet1/0/2 rx b. monitor session 1 source vlan 10 - 20 tx c. monitor session 1 destination interface gigabitethernet1/0/2 d. monitor session 1 source interface gigabitethernet1/0/1 tx e. monitor session 1 source interface gigabitethernet1/0/1 rx correct answer: bc section: mix questions monitor session 1 destination interface GigabitEthernet 2/41 - 48 ^ % Invalid input detected at '^' marker. D. RSPAN traffic is split between VLANs 222 and 223. Specify the characteristics of the source port (monitored port) and RSPAN session. For session_number, the range is 1 to 4. The following example shows how to configure SPAN session 1 to monitor bidirectional traffic from source interface Gigabit Ethernet 2/1 and destination interface Gigabit Ethernet 2/4: Switch# configure terminal Switch (config)# monitor session 1 type local Switch (config-mon-local)# source interface gigabitethernet 2/1 This technique allows a security tester to connect to each switch and collect a representation of the network traffic that exists locally within or transfers via uplinks through the switch. E. A switch can support only one local SPAN session at a time. . console (config)#monitor capture mode file. This is often a . Switch(config)# no monitor session 1 source interface gigabitethernet1/0/1 rx . It worked when I did: #monitor session 1 destination interface GigabitEthernet 2/48 And I can see packets on G2/48 like I should. B. RSPAN traffic is sent to VLANs 222 and 223. I also tried #monitor session 1 destination interface GigabitEthernet 2/41 , 2/48 and it errored out as well. The RSPAN VLAN is replaced by VLAN 223. Also, interface ranges such as fa 0/25 - 26 are possible, and interface list, such as fa 0/24,fa 0/26, if you would like to monitor several clients at the same time. A session can have up to eight source ports and one destination port with the same session number. The password is cisco. Valid interfaces include physical interfaces and . Optional. monitor session source { interface | vlan } [ both | rx | tx ] monitor session destination 16166 gigabitethernet0/1 port-channel 1 VLANvlan 10 Define the capture mode to be file to save it in flash. Valid values are 1 and 2. source. A. Specifies the SPAN source. monitor session session number source interface interface-id rx.

A. monitor session 1 source interface port-channel 6 B. monitor session 1 source vlan 10 C. monitor session 1 source interface FastEthemet0/1 rx D. monitor session 1 source interface port-channel 7, port-channel 8 So we used the CLI command 'monitor session', to port mirror ports 1-23 (Source ports) and made port 24 the destination port. session-number. To create a SPAN source session to monitor the traffic that is bridged into a source VLAN, use the monitor session session_number source vlan vlan-id command. Open User Access Verification edledge-switch# conf t edledge-switch (config)# monitor session 1 source interface port-channel 1 both Destination Interface C2960(config)# monitor session 1 source interface range fe 0/1 - 23. set associated-interface <interface name> set type ipmask set subnet <IPv4 address> <mask> or <IPv4 address/mask> next end When using the "set subnet." syntax, the mask definition can be denoted in bits. For interface-id, specify the source port to monitor. By default, ERSPAN monitors all traffic, including multicast and Bridge Protocol Data Unit (BPDU) frames. a. e0/0 will monitor traffic in both ingress and egress directions b. e0/1 will monitor traffic in a egress directions c. e0/2 will monitor traffic in a egress directions d. e0/3 will monitor traffic in a egress directions e. copied traffic is sent out e0/1 f. copied traffic is sent out e0/3 Answer: A B F 22. These commands have been added to the configuration of a switch. interface-name. It can be a list or a range. Here we can select either rx or tx or both flow as source traffic. destination. cisco monitor session vlan. Optional. Jack Dorsey, then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group. tpw-sw1(config)#monitor session 1 destination interface GigabitEthernet 1/2 Verify your SPAN port setup. What is the result when a technician adds the monitor session 1 destination remote vlan 223 command? Switch(config)# monitor session 1 source interface gigabitethernet0/1 Switch(config)# monitor session 1 destination interface gigabitethernet0/2 encapsulation replicate Note: Switches 2940, 2950, 2955, 3550 use "dot1q" in place of "replicate" Switch(config)# end This example shows how to remove port 1 as a SPAN source for SPAN session 1: Otherwise, I would recommend 'monitor session 1 vlan 12 tx' for simplicity. tpw-sw1(config)#monitor session 1 source interface GigabitEthernet 1/1 The Destination is the port you have the network analyzer connected to. This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on all ports . The interface type and number. Which command flags an error if it is added to this configuration? Specifies the SPAN destination. The interface specified must already be configured as a trunk port. C. An error is flagged for configuring two destinations. Telnet from S1 to R1. On the NetVanta 1550 we port mirrored switch port 24 (uplink port servicing / connected to the NetVanta 1534 switch) as the source. tpw-sw1#show monitor Session 1 --------- Type : Local Session Show Suggested Answer For example, building off of your example, I need an additional port mirror so that in addition of mirroring port 8 on port 1, I'd need to monitor port 12 on port 14. A session can have up to eight source ports and one destination port with the same session number. Tunnel interface supported as source ports for an ERSPAN source session are GRE, IPinIP, SVTI, IPv6, IPv6 over IP tunnel, Multipoint GRE (mGRE) and Secure Virtual Tunnel Interfaces (SVTI). It can monitor only traffic that ingresses or egresses on the source interface or VLAN.C. This is good for when you ONLY want to monitor specific vlan traffic between switches because you will not be able to use the filter AND add the vlan as a source at the same time. Firmware 9.4 added support for flow-based monitoring on the S4810, S4820T, S6000, and Z9000 platforms Commands Used to Set Up On the port monitoring configure enter flow-base enable. monitor session session number filter .
