The stack member numbers The switch stack applies match. A break in any one of the cables will result in the stack bandwidth being reduced to half of its full capacity. as shown in Figure 3.

Which set of configurations will result in all ports on both switches successfully bundling into an EtherChannel? A.Reference: http://www. switch1 channel-group 1 mode on switch2 channel-group 1 mode auto D. switch1 channel-group 1 mode desirable switch2 channel-group 1 mode auto Correct Answer: D Section: Layer 2 Technologies Explanation Explanation/Reference: Explanation: The different etherchannel modes are described in the table below: Mode Description . switch1 channel-group 1 mode desirable switch2 channel-group 1 mode passive C.

·An interface in the auto mode can form an EtherChannel with another interface in the desirable mode. auto Places an interface into a passive negotiating state. Reference: http://www. in which the interface starts negotiations with other interfaces by sending PAgP packets. An interface in the auto mode cannot form an EtherChannel with another interface that is also in the auto mode because neither interface starts PAgP negotiation.cisco. in which the interface starts negotiations with other interfaces by sending LACP packets. for Layer 2 EtherChannels. With the on mode. A monitor session on the distribution switch with a physical interface as the source and the remote SPAN VLAN as the destination . An interface in the on mode that is added to a port channel is forced to have the same characteristics as the already existing on mode interfaces in the channel. Both the auto and desirable PAgP modes allow interfaces to negotiate with partner interfaces to determine if they can form an EtherChannel based on criteria such as interface speed and. Which three items must be configured to mirror traffic to a packet sniffer that is connected to the distribution switch? (Choose three. in which the interface responds to LACP packets that it receives. desirable Places an interface into an active negotiating state.1_13_ea1/ configuration/guide/3550scg/swethchl. but does not start LACP packet negotiation.)

This setting minimizes the transmission of LACP packets. on Forces the interface into an EtherChannel without PAgP or LACP. A network engineer wants to analyze all incoming and outgoing packets for an interface that is connected to an access switch. This setting minimizes the transmission of PAgP packets.html QUESTION 5 Refer to the exhibit.com/c/en/us/td/docs/switches/lan/catalyst3550/software/release/12. For example: ·An interface in the desirable mode can form an EtherChannel with another interface that is in the desirable or auto mode. Interfaces can form an EtherChannel when they are in different PAgP modes as long as the modes are compatible.

Each RSPAN source switch must have either ports or VLANs as RSPAN sources.cisco. source VLANs.html . A monitor session on the distribution switch with a remote SPAN VLAN as the source and physical interface as the destination E. enabling remote monitoring of multiple switches across your network. The RSPAN traffic from the source ports or VLANs is copied into the RSPAN VLAN and forwarded over trunk ports carrying the RSPAN VLAN to a destination session monitoring the RSPAN VLAN.2_55_se/ configuration/guide/3750xscg/swspan. A monitor session on the access switch with a remote SPAN VLAN source and the physical interface as the destination F. A remote SPAN VLAN on the distribution and access layer switch C. SPAN copies (or mirrors) traffic received or sent (or both) on source ports or source VLANs to a destination port for analysis.B. The destination is always a physical port Reference: http://www. A monitor session on the access switch with a physical interface source and the remote SPAN VLAN as the destination D. and destination ports on different switches (or different switch stacks).com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12. A monitor session on the distribution switch with a physical interface as the source and a physical interface as the destination Correct Answer: BCD Section: Layer 2 Technologies Explanation Explanation/Reference: Explanation: You can analyze network traffic passing through ports or VLANs by using SPAN or RSPAN to send a copy of the traffic to another port on the switch or on another switch that has been connected to a network analyzer or other monitoring or security device. The traffic for each RSPAN session is carried over a user-specified RSPAN VLAN that is dedicated for that RSPAN session in all participating switches. RSPAN supports source ports.
