If the upgrade has completed but the patch is not loaded before the upgrade, the system cannot operate. Perform the following operations to solve the problem: Change the system MAC address to the factory MAC address (ending with 0) of the multi-MAC MPU, and then restart the switch. The ...
If the server is unavailable, the phone cannot access the voice network and therefore cannot operate. For data traffic, you can configure inaccessible authentication bypass, or critical authentication, to allow traffic to pass through on the native VLAN when the server is no...

WAN-MACsec will operate at Layer 2 and at line speed, making it a more appealing solution. In terms of support: IPsec is supported only on the Catalyst 9500X-60L4D. None of the other products, including the Catalyst 9500X-28C8D, support IPsec. At the time of writing this docum...
Since Ethernet switches operate on local area network frames at the Data Link Layer, you will sometimes hear them called link layer devices, as well as Layer 2 devices or Layer 2 switches.[3] Transparent Bridging Ethernet switches are designed so that their operations are invisible to the ...
(g),(h) The optical electric field distribution of the proposed electro-optic switch at the resonance wavelength of 1548 nm for the (g) amorphous phase and (h) the crystalline phase of the PCM layer. Full size image MZI based non-volatile hybrid plasmonic switch In this section, we ...
Long latency in obtaining monitoring information may lead the state replacement module to operate with stale data, resulting in poor hardware offload efficiency due to inaccurate decisions. 2.3. Policy to support dynamic workload The state replacement policy is primarily responsible for the hardware ...
If you configure the interface to provide other services, both BFD MAD and other services might operate incorrectly. ¡ Disable the spanning tree feature on all Layer 2 Ethernet ports in the BFD MAD VLAN. The MAD feature is mutually exclusive with the spanning tree feature. MAC addres...
OpenFlow 1.2 and later OpenFlow 1.2 and later allow flow deletion commands, but not other flow table modification commands, to operate on all flow tables, with the behavior described above for OpenFlow 1.0. metadata=value[/mask] Matches value either exactly or with optional mask in the ...
As briefly discussed at the beginning of this article, switches belong to Layer 2 of the OSI model. They operate at the Data Network layer and their main task is to forward ethernet frames from one port to another as fast as possible. However, there are some more advanced switches that ca...
