Is it possible to Ping but can ARP?
The fact that you see the MAC addresses of these backup servers in the ARP table of your VSS suggests that these servers are actually able to communicate with your VSS. I really suggest verifying all possible firewalls somewhere on the way towards these servers.
Can you see device MAC address in ARP table?
But if I look into the ARP table with arp -a, I can not see any of the devices that responded to my ping request. I only can see the broadcast IP and MAC address in the table (10.11

Can a Cisco 6509 router Ping a server?
The 6509’s act as Router/Switch, have servers on my backup network that are physically connected to this VSS. However, I am having problem being able to ping SOME of these servers, I can arp but not ping from the Switch/Router.
Which is better ARP or Windows Live network?
I think arp is more broadcast so the first signal back wins. If there is no other computer using the ip address.. try a different network card before you go nuts. no, its a windows 2000 box, first time on a live network.
Why am I not getting an ARP reply with this request?
Why am I not getting an ARP reply with this request? Using pcap_sendpacket in C, I’m manually sending the following packet on wlan0 (I’ve left out some fields, but I think they are correct): Using Wireshark to listen on wlan0, I expect to see an ARP reply giving me the MAC address of a Google server.
When does device X receive an unsolicited ARP reply?
If device X receives an ARP reply it did not ask for, that reply is unsolicited. An ARP reply is usually a response to an ARP request broadcast from device X along the lines of “what is the MAC hardware address for the IP address a.b.c.d?”
Is the ARP table on the same command line?
It is the same command line on macOS, Windows, or Linux. You may need to populate/refresh the ARP table by pinging the local network’s broadcast address, e.g. if local network is 192.168.1.x with a mask of 255.255.255.0, then you would ping 192.168.1.255.
Why do I get no answer on ARP requests?
No answer on arp requests? I have a problem where my Layer 3 Dell PowerConnect 6248 Switch (main switch) will sometimes (that means sometimes it works, sometimes it won’t) not get an arp response from a device behind Dell PowerConnect 2824 (edge switch). If the Client is on same vlan as Device, there is no problem and traffic always flows.
When do you need to create an ARP entry?
ARP entries are created only when they’re needed. The first time you need to communicate with an IP on the local network, your device broadcasts an ARP query, then caches the response. There’s nothing that proactively fills in the cache for all IPs on the LAN.
