FUNCTION Commands supported only on the Brocade FR4-18i blade
SYNOPSIS portshow option [slot/]ge_port [all | tunnel_id ] [arguments]
DESCRIPTION Use this command to display configuration parameters and status information for FCIP tunnels on the
Brocade FR4-18i blade. The following display options are supported:
• portShow fciptunnel - Displays Fibre Channel over IP (FCIP) tunnel configuration settings
including the following:
- Additional performance parameters
- FC data path credit data
- Connection parameter information
- IKE and IPSec policy information on IPSec-enabled tunnels
- VC to FCIP QoS mapping table
- FCIP TCP Byte Stream statistics on Byte Stream-enabled tunnels
- History of TCP connections
- SnapShow capture of TCP statistics between two points in time
• portShow mode - Displays Port Mode information.
• portShow ficon - Displays FICON parameters on FICON-configured tunnels.
Each GbE port is associated with a TCP history, which tracks the state of statistics at the moment of a
TCP connection failure. An entry is logged for the TCP connection when it encounters any of the
following failures:
• Maximum number of retransmits is exceeded (MAX RTX)
• Maximum keep alive timeout is exceeded (KEEPALV TO)
• RST packet is received (RESET RCVD)
