Dell Brocade G620 Brocade 8.0.1 Fabric OS Command Reference - Page 273

fcPing --pattern pattern Specifies up to 16 "pad" bytes, which are used to fill out the request frame payload sent. This is useful for diagnosing data-dependent problems in the fabric link. The pattern bytes are specified as hexadecimal characters. For example, --pattern ff fills the request frame with instances of the number 1. If a non-byte-aligned pattern is specified, the upper nibble of the last pattern byte is filled with zeros. For example, --pattern 123 fills the payload with a pattern of 0x1203. --bypasszone Bypasses the zone check. --quiet Suppresses the diagnostic output. Only zoning information, if applicable, and the summary line are displayed. The following operands are valid only when fcPing is executed to perform a SuperPing: --allpaths [args] destination Executes a SuperPing that covers all available least-cost paths to the specified destination. The number of actual paths covered depends on two other parameters that you can optionally specify. When you issue fcping --allpaths for a destination without any other options, SuperPing covers all ISLs in the routes between source to destination but does exercise all possible combinations of end-to-end paths. This operand is required when executing fcPing as SuperPing. The following operands are optional and valid only with the --allpaths option: -printisl Displays statistical data for each ISL and internal port along the paths traversed by SuperPing. This information displays in addition to the path display. -covcount N Specifies the minimum number of times each ISL is exercised by the SuperPing command. The command sends N frames and checks if each ISL is exercised at least N times. When the condition is met, superPing exits and prints the statistics. The default value is 5. -maxtries M Specifies the maximum number of frames to be sent before SuperPing exits. If both -maxtries and -covcount are specified, SuperPing checks the ISL coverage and keeps resending frames until the minimum coverage condition to is met or until the maximum number of echo frames specified in maxtries has been sent. For example, assuming a coverage count of 100 and a Maxtries value of 300, SuperPing will send 100 frames at a time and checks if each ISL is covered at least 100 times. If not, SuperPing will keep sending 100 frames at a time to check for coverage up to 3 times for a maximum of 300 frames (3*100 = 300) on each egress port. If this value is set too low in relation to the specified coverage count, not all ISLs may be covered. The default value is 100. -delay D Includes a delay of D milliseconds between each echo frame sent. -framelength len Specifies the size of the data to send.
