JNCIS-ENT Switching and Routing Study Guide |

This is not necessarily a bad thing. If MAC limiting is enabled and a violation occurs, the MAC address is discarded or in other words is not added to the bridge table. Guidd EX Series switches also support Virtual Chassis functionality, but you must include an external routing engine XRE to handle most of the routing engine functions.

The EX is designed to support Virtual Chassis technology and can be combined with the EX switches within a single Virtual Chassis configuration to support environments where both GbE and 10 GbE servers are present. This configuration option stores the database file either etn or remotely, depending on user preference, and is jnciw under the [edit ethernet-switching-options secure-access-port] hierarchy level.

The PFE is responsible for forwarding transit frames, packets, or both through the switch.

If it is any consolation, there has been a lot of progress over the years. By contrast, stateful firewall filters not supported on EX Series switches only require you to permit the initial connection and then automatically permit bidirectional communications for this connection.

If CoS guidr used in a network, it should be incorporated consistently in all three layers. IP source guard applies its checking rules to packets sent from untrusted access interfaces on those VLANs.

Does Juniper intend to develop updated Study Guides for routkng prep?

Processing fragments is trickier with stateless firewall filters than with a stateful firewall filter. The lowest bridge ID determines the root bridge.

In this example, you can see the individual counters incrementing which indicates devices, using unexpected MAC addresses, are attempting to gain access to the network using the highlighted access ports and that unauthorized STP BPDUs are being received on one or both of the defined VLANs. Virtual Chassis This Chapter Discusses: You can use many header fields as match criteria. Each interface has an associated cost that is based on the configured speed.

In some implementations you can have an IP phone and a PC both connected to a single switch port, in a daisy-chained fashion. This site uses cookies.

With this setup in place, host-a1 and host-a2, should now be studyy to communicate through the switched network. The MAC limit is user defined and varies depending on the needs within each environment.

Locate the specific software or hardware release and title you need, and choose the format in which you want to view or print the document. By default, on EX Series switches, access interfaces are untrusted and trunk interfaces are trusted.

The port has transitioned and the switch continues to learn MAC addresses. The port is not used in active topology. On EX Series devices, network ports operating in full-duplex mode are considered point-to-point links, whereas network ports operating in half-duplex mode are considered shared LAN links.

If you specify an action modifier but do not specify a terminating action, the switch imposes an action of accept.

Stateless firewall filters examine each packet individually. Unlike some Junos devices, firewall filters applied jjcis the loopback interface do not affect traffic traversing the management Ethernet interface me0. Spanning Tree This Chapter Discusses: Part 1 This and the next graphic illustrate sample configurations used to meet the objectives listed on the previous graphic.

The actual match conditions available for each of the Chapter 5—8? An interface operating at 10 Mbps assumes a cost of routiny, an interface operating at Mbps assumes a cost of , an interface operating at 1 Gbps assumes a cost of 20, and an interface operating at 10 Gbps assumes a cost of As you begin to recognize these problems, you can gain confidence in that you understand the concepts and technology required for passing this exam.
