Sep 25, 2017 · UDP port 7 is used with WoL (Wake On LAN) implementations. If done on the internet, this is sometimes referred to as Wake on Internet. Personally, I'd never have this open from the internet, as the lack of authentication on WoL packets allows virtually anyone to turn on computers by "guessing" MAC addresses.

Samuel schrieb: There is a lot of debate on the Internet regarding ICMP being layer 3 or layer 4, as supposedly it uses port 7 for the latter as an echo reply (I did see someone comment that port 7 was for the old ICMP service); any input would be appreciated.

I can add to what they have said already that switches usually always start with /1 whereas routers always start with /0. So for a two port router you might find g0/0 and g0/1 and for a 24 port switch you will normally see fa0/1 through to fa0/24. To see all the ports on a router or switch you just need to run the command show ip interface brief.

6) Back in the Terminal, you must add the new web server port to the allowed incoming ports list of the firewall. To do so, enter the command "sudo firewall-cmd --add-port=<your-new-port>/tcp --permanent" (without quotes and replace <your-new-port> with the new port your configured in the previous steps) and press ENTER.

The device cannot automatically negotiate the Ethernet port speed and duplex mode if the connecting port is configured to a value other than auto. GIF Caution Changing the Ethernet port speed and duplex mode configuration might shut down and reenable the interface.

6. **Documentation and Reporting**: Create a report based on your findings, including recommendations on the necessary address blocks and port allocations. 7. **Tools**: Some tools that can assist in sizing NAT include: - IP Address Management (IPAM) tools to track and allocate IP addresses. - Network simulation tools to model traffic patterns.

Fa0/7 desirable n-isl trunking 1. Fa0/8 desirable n-isl trunking 1 . Port Vlans allowed on trunk. Fa0/7 1-4094. Fa0/8 1-4094 . Port Vlans allowed and active in management domain. Fa0/7 1,10. Fa0/8 1,10 . Port Vlans in spanning tree forwarding state and not pruned

Valentina, A MAC flap is detected, when a MAC address is learned on a new port within the 300-second CAM table refresh window. Normally in a properly configured network, that doesn't happen, because on Access layer switch, when you physically remove patch lead from one port and connect it to another, the original port goes to notconnected mode and all its MAC entries are purged instantly, so ...

6. Now learn the configuration of telnet access to the switch from the PCs Ethernet port. 7. If you already know that, take 3 L2 switches - 2950 / 2960, connect them to each other in a "triangular" fashion, and start with STP. 8. It all depends on what all you know about operations of switches.
