How does a single Aruba CX 6300M switch configuration use L3 connectivity to establish routing traffic between switch virtual interfaces 120 and 130?
On an Aruba CX 6300M switch, routing between Switch Virtual Interfaces (SVIs) is enabled by default. Therefore, traffic between SVIs, like 120 and 130, can be routed internally without the need for additional configuration such as route leaking or static routes, as long as there is no 'no routing' configuration present on the SVIs.
The customer requires two Aruba CX 6200F 48G switches to be connected to each other with a distance of 80m/252ft between wiring closets. Switches need to have reservation for VSF expansion with ring
topology in each cabinet.
What is a valid configuration for a redundant link-aggregation port configuration?
For an 80m distance between wiring closets, using SFP+ transceivers is appropriate as they can support longer distances than standard copper interfaces. Ports 1/1/51 and 1/1/52 are typically reserved for uplinks on Aruba CX 6200F 48G switches and can support SFP+ transceivers, making them suitable for a redundant link-aggregation port configuration.
What is used by network devices to send error and operational information related to IP communications?
ICMP (Internet Control Message Protocol) is used by network devices to send error and operational information related to IP communications. It is used to send messages like 'destination unreachable' or 'time exceeded' when there are issues in IP communication
A network technician is testing a new SSID for a branch office. They are able to connect, get an IP address, and resolve DNS names. However, they are not able to browse the internet.
On the existing SSID at the branch, connectivity to the internet works as expected on the same VLAN as the new SSID. The wireless client should have received a new role to allow internet access.
What should the network technician verify to ensure both SSIDs function in a similar way?
When a network technician encounters an issue where a new SSID does not allow internet access despite successful connectivity and DNS resolution, they should verify the firewall policies associated with the new SSID. The firewall policies must include rules that permit traffic to and from the internet and should be correctly ordered to ensure that they are applied as intended. Since the existing SSID functions correctly, comparing the firewall rules between the two can be a useful method of troubleshooting.
When does the 802.1x authentication process begin when connecting to a secured enterprise mode WLAN?
The 802.1x authentication process begins after the client device completes the 802.11 association with the access point but before the WPA 4-Way Handshake. This is part of the EAP (Extensible Authentication Protocol) process, which authenticates the device before allowing full network access.
