How do you enable ICMP on a cisco?
To enable ICMP (Internet Control Message Protocol) on a Cisco device, you typically need to ensure that the device's access control lists (ACLs) allow ICMP traffic. If you have an ACL that is blocking ICMP, you can modify it to permit ICMP packets by adding a rule like permit icmp any any. Additionally, make sure that any firewall features or security settings on the device do not block ICMP traffic. Once configured, you can test ICMP connectivity using tools like ping.
Why is it that an ICMP packet does not have source and destination port?
Because ICMP is on the network layer
Which ICMP message contain part of the ip datagram?
All ICMP Error Messages
What is the purpose of including the IP header and the first 8 bytes of datagram data in the error reporting ICMP message?
To match the packet to the process that sent it.
Where the icmp request are originated?
icmp request is orginated on the OSI network layer with ip protocol.
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 the purpose of controlling the environment when testing a hypothesis?
The purpose of controlling the environment when testing a hypothesis is ultimately to get a reliable result to the study.
Which protocol should be allowed when not able to ping a remote device residing behind a firewall?
ICMP is the internet control access protocol . ICMP is the plrotocol that should be allowed when not able to ping a remote device residing behind a firewall. ICMP is the protocol of network layer.
What is the response if a host sends a ICMP to a default gateway?
If devices on a network are properly configured, a host sending ICMP to a default gateway must receive a reply. ICMP simply means ping.
