3. Can the router use the private IP to set up the remote connection function? Please note that if the router is using a private WAN IP address (such as connected behind another router/switch/modem with built-in router/Wi-Fi feature), could potentially place the router under a multi-...
By default, all ports of a switch are enabled. As we are talking aboutlayer 2 switching, there is no need to configure IP address or any routing protocol on the switch. In such a situation, the configuration is not focused on the switch. Cisco Switch - The Normal Configuration The normal...
Option 24: carries the ACs' IPv6 domain names. The following figure shows an example of a DHCP Response message carrying Option 43. If DTLS is enabled on the AC, the AC informs the AP of the DTLS status through the Discovery Response message. The AP then starts DTLS negotiation to establ...
"I set up a switch, but I want to be able to access it; however, I can't access it via Telnet or HTTPS. I believe the problem is that I did not set up the username. Is there any way to access it remotely? I am attaching the main setup. enable secret 9 $9$KkMgIVNmfnRs5E...
If load imbalance or hash polarization occurs during traffic forwarding, you can adjust the hash algorithm on the device to resolve the problem. For example, for an inter-device hash polarization scenario similar to that shown in Hash Polarization, the hash algorithm on Switch A can...
On Cisco Nexus 9500 Series switches, the default ingress TCAM region configuration has one free 256-entry slice in Cisco NX-OS Release 6.1(2)I1(1). This slice is allocated to the switch port analyzer (SPAN) region in Cisco NX-OS Release 6.1(2)I2(1). Similarly, the RACL region is ...
You must also enable IPv6 routing because it’s disabled by default. You can add a next-hop address for any configured route or an exit interface. We will use the simple topology in Figure 13.6 below, which uses EUI-64 addressing on Fast Ethernet interfaces and has a manually added ...
Make sure you use the –a switch with the IP address, not the host name. If everything is working fine, you should get a response from DC1 that looks something like the ping response inFigure 3. Notice that instead of simply resolving the IP address 192.168.1.200, Ping also resolved the...
If a port never has a switch connected to it, you can use the spanning-tree bpduguard enable command. Since the routing protocols are the bread and butter of a router’s control plane, securing them is a must. Border Gateway Protocol (BGP) is a robust, complex routing protocol tha...
