Perform the following procedure to configure and enable FC Fastwrite.
Create a zone configuration to filter FC Fastwrite flows. FC Fastwrite flows are configured by creating a
1.
zone name with an fcacc token as a prefix. For LSAN configuration, use lsan_fcacc as a prefix, as
shown in the following example:
#zonecreate fcacc_myzone1, "initiator-wwn; target-wwn"
#zonecreate LSAN_fcacc_myzone2, "initiator-wwn; target1-wwn; target2-wwn"
#cfgcreate mycfg, "fcacc_myzone1; LSAN_fcacc_myzone2"
#cfgenable mycfg

this command disrupts data traffic. For the FR4- 1 8i blade, the command powers the blade off and back
on. In the case of the 400 Multi-Protocol Router, the router is rebooted. The process takes up to five
minutes.
switch:admin> fastwritecfg --enable slot
where slot is the slot number in which the FR4- 1 8i blade is installed. A slot number is not required for
the 400 Multi-Protocol Router.
