Wireshark packet sniffer doesnt work mac

Protocol number used by the data in a data packet. Table 1-2 Description of the capture-packet cpu command output # Capture packets sent to the CPU, parse basic information, and display the information on the terminal (packet captured in the diagnostic view of the S5720HI is used as an example). The switch can parse basic information about the captured packets only when this parameter is specified and the length of the captured packet is greater than or equal to 48 bytes (that is, the value of packet-len length is greater than or equal to 48). This parameter can be specified only when this command is run in the diagnostic view. Parses basic information about captured packets, such as the source and destination MAC addresses or IP addresses. The value is an integer in the range from 20 to 64, in bytes. Specifies the length of captured packets. The value is an integer in the range from 1 to 1000. The system stops capturing packets after the specified number of packets are captured. Specifies the number of packets to be captured. The value is an integer in the range from 1 to 300, in seconds. The system stops capturing packets after the specified timeout interval expires. Specifies the timeout interval for capturing packets. The value of file-name is a string of 5 to 63 characters.

terminal: Displays captured packets on a terminal.

file file-name: Saves captured packets to a file.

Indicates the mode in which captured packets are stored: Only the S5720EI, S5720HI, S5730HI, S6720EI, S6720HI, S6720S-EI, and modular switches support this parameter.ĭestination * The value is an integer in the range from 1 to 4094.Ĭaptures packets with a specified inner VLAN ID.

ipv6-acl: The value is an integer in the range from 2000 to 3999.For other fixed switches, the value is an integer in the range from 2000 to 4999. ipv4-acl: On the S5720EI, S5720HI, S5730HI, S6720EI, S6720HI, S6720S-EI, and modular switches, the value is an integer in the range from 2000 to 5999.For other fixed switches excluding the S5720EI, S5720HI, S5730HI, S6720EI, S6720HI, and S6720S-EI, the destination IPv6 address cannot be specified in an ACL6 rule. The specified ACL or ACL6 and the corresponding rules must have been created. The interface must exist on the switch and cannot be a management interface.Ĭaptures packets matching a specified ACL or ACL6. interface-numberspecifies the interface number.interface-type specifies the interface type.Interface interface-type interface-numberĬaptures packets on a specified interface.
