How to enable VLAN communication between two core switches
This option is called router on a stick (ROAS) and allows all VLANs to communicate through a single interface. Use a Layer3 switch, a device that performs both the switching and routing operations. Download the guide and refer back to it at any time! Cisco recommends to. This document describes how to configure Inter-VLAN routing with Cisco Catalyst series switches. Cisco recommends that you have knowledge of these topics: The information in this document is based on these software and hardware versions: The information in this document was created from the devices. Inter-VLAN routing is a network configuration technique that allows communication between devices on different VLANs (Virtual Local Area Networks) within the same network VLANs are commonly used to segment a network, improving performance and security by isolating traffic within each VLAN. Because the use case is so common, network administrators need to understand inter-VLAN routing. Segmentation: VLANs limit broadcast domains, reducing unnecessary traffic.

Hi, can anyone advise whether it is saft to run debug commands "debug platform software memory <process> <R0/R1/RP xxx > alloc callsite start " and "debug platform software memory. alloc backtrace start " ? on c9407r switch? we saw the error log on the switch. Is it software bug? the XE OS. Is this a good idea to perform a "maintenance" reboot just because? There's a pretty good chance that on a 6500 these days that a reboot or powercycle of the chassis you'll have at least something die. Both 10 gig ones. External JTAG equipment can be used to: Download and debug programs. Download new images to the PLD on the Core Tile or to FPGAs or PLDs present on other attached boards.
