What else can I help you with?
Why filtering ICMP traffics by ACLs is not advised?
Because ICMP traffic, notably ICMP ECHO REQUEST-0 and ECHO REPLY-8 are used in network diagnostic sequences.
What is an echo request relative to computer networking?
Part of the ICMP protocol that requests a reply from a computer.
What port is used for icmp echo re quest?
There really is no "port" for icmp but there is a icmp code. If you are looking for the icmp code for echo-reply it is 0 and the echo is 8 For an access list you could do the following: permit icmp any any echo-reply permit icmp any any echo Or the same using the icmp code permit icmp any any 0 permit icmp any any 8
What is an echo-request?
An echo-request is a sort of ICMP (Internet Control Messaging Protocol). This protocol is used to check and control the IP packet traffic.For example, ping and traceroute packets are echo requests.

When you use a ping command in microsft if its successful 5 exclamations are displayed whereas it is different on cisco why?
The ICMP protocol is standardized, in the sense that a computer should reply with a certain message (called "echo-reply") if it receives a certain other message (the "echo-request"). How many echo-request messages are sent when the user types "ping" is NOT standardized - there is no need to.The ICMP protocol is standardized, in the sense that a computer should reply with a certain message (called "echo-reply") if it receives a certain other message (the "echo-request").

Which port does ping uses?
The answer is none.No ports required for Ping as it uses icmp packets.It needs to allow icmp 'echo-request' (type 8) packets out and icmp 'echo-reply' (type 0) packets in.If you need to check the availability of a port, you must use a different tool, such as Paping.It doesnt use any port. Echo request is an ICMP message which is an Internet Layer Protocol so it is sent as an IP datagram.If you need to check the availability of a port, you must use a different tool, such as Paping.
What transport layer protocol does ping use?
Assuming IPv4 ICMP. Ping uses IP for transport. Ping in itself is an "Echo Request", which is a function of the ICMP protocol. The IP Packet will carry the ICMP protocol from end-to-end. ICMP has a protocol number of 1, so the "Protocol" field in the IPv4 header will contain "1" as a reference to the ICMP payload. For IPv6, ICMPv6 is used, and the transport will be IPv6.
What does ping response mean in C?
To ping is to issue an ICMP Type 8 (ICMP Echo Request) to a host which according to RFC1122 it must reply to. (In reality this may be seen as a security risk.). The format of a successful response has type and code of 0. If you're operating down at this level you'll need to examine ICMP in more detail. If you have a sockets interface then you may just get a reply event. Sometimes people call these "pongs". ie Ping? Pong. Ping? Pong.
How do you stop excessive pings to your server?
Block them at the router. Understand, however, that ICMP Echo Request/Reply (Ping) is a standard network troubleshooting tool, and that disabling it can compromise the ability to troubleshoot certain problems.
What protocol does ping use?
"Ping uses the Internet Control Message Protocol (ICMP) Echo function which is detailed in RFC 792"http://www.activexperts.com/activsocket/tutorials/ping/So the short answer is that it uses the ICMP protocol.
How to work ping?
The "ping" program uses ICMP echo message requests and listens for ICMP echo message reply messages from its intended host. Using the -R option with ping enables the record route feature. If this option is used ping will set the record route (RR) in the outgoing ICMP IP datagram. Website:http://www.iyogibusiness.com/
