All the tests were from the internal debug message point of view of the switches. If one side is shut down and the other is not, the status on the enabled side is notconnect (because it does not sense a neighbor on the other side of the wire). In order to decide where to send a frame, the switch looks at the destination MAC address in a received frame and looks up that destination MAC address in the CAM table.

You do not even need an account for this documentation; it is available to anyone. D] Description/name of port. If you had workstations that send packets through the switch to a destination on the other side of the channel, you would expect to see traffic that goes over each of the four links in the channel. 05), the switches default to this: Portfast is enabled on the Ethernet (10Mbps) ports, and Portfast is disabled on the fast Ethernet (uplink) ports. For the version of software, you run (V8. You again turn the port off and on and record the time. Understand the Spanning Tree messages. Show logging- see what type of messages generate logging output. Lab 7-3: testing mode: connect a computer to a network printer. C] Path cost (spanning tree) 10. All you need to do is turn on Portfast and turn off PAgP (if present) to solve the problem, but if you need to eliminate every possible second you could also set the port speed and duplex manually on the switch if it is a multi-speed port (10/100). 2/2 connected off not channel...

2900XL(config)#int f0/1. For example, if a PC is not able to log in to a server across your network, there are many things that can be wrong. To the second switch, the MLS-RP appears as an external router since the MLS-RP and MLS-SE are not contained in the same chassis. Switch-A (enable) set port duplex 2/1 full. Lab 7-3 VPN Technologies and Services Flashcards. Note: Dependent upon the hardware, there can be additional restrictions. The CAM table shows which port the frame must be sent out in order for that frame to reach the specified destination MAC address. The native VLAN is central to 802. Troubleshoot Ethernet 10/100Mb Half/Full Duplex Auto-Negotiation.

Theshow port capabilitiescommand shows that this port has the ability to trunk and to create an EtherChannel. For example: check the physical connections involved (layer 1); check connectivity issues within the VLAN (layer 2), and check connectivity issues across different VLANs (layer 3), and so on, If there is a correct configuration on the switch, many of the problems you encounter are related to physical layer issues (physical ports and cables). 1q method for trunking. The pings began to fail. Designated Root Port 2/24. Bridge ID MAC ADDR 00-90-92-b0-84-00. They do this with the addition of tags to the packets; this indicates to which VLAN the packet belongs. Lab 7-3: testing mode: connect a computer to a network solutions. If a port has a solid orange light, that means that software inside the switch shut down the port, either by way of the user interface or by internal processes.

This was the time it took to negotiate the link and do DTP and PAgP tasks. In addition, a bare minimum of Catalyst OS 4. First, verify that channeling isoff. Remember that the point of MLS is to create a shortcut between two VLANs, so that the routing between the two end devices can be performed by the switch, and this frees the router for other tasks. Let us look at other things that could slow the port as it reaches the forwarding state. Note: If the port status becomeserrdisable, you must specifically enable the ports with theset port enablecommand for the ports to become active. In order to turn on Portfast, do this: In order to verify that Portfast is enabled, use theshow spanning-tree interfacecommand.

In order to verify that the channel is setup properly, do theshow port channelcommand. If your gigabit link does not come up, check to make sure the flow control and port negotiation settings are consistent on both sides of the link. Spanning tree is shown to treat the ports as one logical port in this command. When STP runs it causes all ports that are included in the spanning tree process to become active much slower than they otherwise would, as it detects and blocks loops. Connect the port in question to another port in the same switch just to see if the port links up locally. Question 3 of 5 is 10. 2900XL(config-if)#no shut. The biggest problem you see is that Windows 95/98/NT, Novell, VINES, IBM NetworkStation/IBM Thin Clients, and AppleTalk clients are unable to connect to their servers. You can see from the show port channel command that the PAgP mode is set toauto, which means it channels if asked to by a neighbor that speaks PAgP. A default gateway was assigned to both switches with set ip route default 172. Commands fused to check the installed hardware and software areshow versionon the router andshow moduleon the switch. With new platforms and software released that support IP MLS, it is important to check documentation and release notes, and to generally install the latest release in the lowest train that meets your feature requirements. Ports are the foundation of your switching network.

Thank you this helped. In later Catalyst operating system software (5. Verify that the ports to be grouped have the same settings. You disconnected and then reconnected the cable and recorded how long it took for the switch to respond to the ping with Portfast on and with Portfast off. In this document, the terms EtherChannel, Fast EtherChannel, Gigabit EtherChannel or channel all refer to EtherChannel. A broken fiber cable or other cable/port issues can cause this one-way only communication. Show mac- to view packets received and sent by the switch. This is a synopsis of directions to manually configure the EtherChannel: Show the Cisco IOS version and modules used in this document. The switch configurations were cleared so that they start from the default conditions. BPDU: sent 1001, received 1.
A 100Mb hub shares 100Mb of bandwidth among the connected devices. Enter Selection: Timing Tests on the Catalyst 1900. It is best to set each side for the EtherChannel desirable mode if you want to use EtherChannel. Port(s) 2/1 set to full-duplex. Port Rcv-Unicast Rcv-Multicast Rcv-Broadcast.
The configuration is saved automatically to NVRAM. You need to ensure that the communication between both the router is encrypted using IPSec. Designated bridge has priority 32768, address 40. A Novell IPX networking workstation does not have the "Novell Login Screen" upon bootup. Currently we evaluate by hand the confirmed and continuing students. Total time from shutdown until the port started forwarding was30 seconds(27:27 to 27:57). Destination-IP mode, the default, is in use when no access list is applied to the MLS-enabled interface of the router. The status can be "connected" even if duplex has been incorrectly negotiated or misconfigured. What does matter is that all the ports involved are in the same mode: either they are all trunking before you configure the channel, or they are all not trunking before you configure the channel. A flowmask is a filter configured by a network administrator that is used by MLS to determine whether a shortcut needs to be created. Another cause of inactive ports is when the VLAN they belong to disappears. Confusion can arise here, since it seems that a layer-two device takes on a layer-three task; actually, the switch is only rewriting layer-three information, and is switching between subnets/VLANs--the router is still responsible for standards-based route calculations and best-path determination. If the status light on the switch flashes orange, this usually means there is some kind of hardware problem with the port or the module or the switch.
