![]() If the source and destination belong to multiple VLANs and you specify MAC addresses, you can also specify a VLAN. You can trace a Layer 2 path by specifying the source and destination IP addresses (or IP aliases) or the MAC addresses.All switches in the path must be reachable from each other.You can use this utility from a switch that is not in the Layer 2 path between the source and the destination however, all of the switches in the path, including the source and destination, must be reachable from the switch.(See "Configuring CDP," for information about enabling CDP.) If any devices in the path are transparent to CDP, l2trace will not be able to trace the Layer 2 path through those devices. You must enable CDP on all of the Catalyst 4000 family, Catalyst 5000 family, and Catalyst 6500 series switches in the network.The Layer 2 Traceroute utility works for unicast traffic only.This section lists the guidelines for the Layer 2 Traceroute utility: Information is displayed about all Catalyst 4000 family, Catalyst 5000 family, and Catalyst 6500 series switches that are in the path from the source to the destination. This utility determines the path by looking at the forwarding engine tables of the switches in the path. ![]() ![]() The Layer 2 Traceroute utility allows you to identify the physical path that a packet takes from a source to a destination. This example shows how to check module status on a Catalyst 2948G switch: For example, on a Catalyst 2948G series switch, the 24 Fast Ethernet ports belong logically to module 2. ![]() You must apply configuration commands to the appropriate module. The Catalyst 4912G, 2948G, and 2980G switches are fixed-configuration switches, but are logically modular. You can use the argument to specify a particular module number to see detailed information on that module. You can see what modules are installed, as well as the MAC address ranges and version numbers for each module, by using the show module command. The Catalyst enterprise LAN switches are multimodule systems. Using Secure Shell Encryption for Telnet Sessions.This chapter consists of these major sections: About 30% of the goods handled in the Port of Hamburg already come from China or go to China, it said, adding that the transaction would be finalized soon.ĬOSCO also holds stakes in several other European ports, including Greece’s main port of Piraeus.Note For complete syntax and usage information for the commands used in this chapter, refer to the Command Reference-Catalyst 4000 Family, Catalyst 2948G, and Catalyst 2980G Switches. HHLA said the approval would allow it to become a preferred handling location for COSCO. Two junior partners in Chancellor Olaf Scholz’s governing coalition - the Greens party and the Free Democrats - demanded the cap last year, warning that a larger stake could give China undue control over Germany’s critical infrastructure. The government said it would stick to a compromise agreed to last year barring COSCO Shipping from acquiring more than than 24.99% of the Tollerort terminal of Hamburg port logistics company HHLA. BERLIN (AP) - Germany gave final approval Wednesday for a Chinese company to take a significant minority stake in the operator of a container terminal at the Hamburg port, following concerns that a larger buy-in might pose a national security risk.
