blade first should be enabled for FC fastwrite using fastWriteCfg. This
command can also be used to list all ports configured for FC fastwrite. This
feature requires a Brocade license. The syntax for portcfg fastwrite is as
follows:
portcfg fastwrite [slot/]port mode
Valid modes for fastwrite are:
--enable Enables FC fastwrite on the specified port.
--disable Disables FC fastwrite on the specified port.
vlantag Use this command to maintain the VLAN tag table associated with a
particular network interface. This table is mainly used by ingress processing
to filter VLAN tagged frames. If a VLAN tagged frame is received from the
network and there is no entry for the VLAN ID, the frame is discarded. There is
no ingress filtering on the destination IP address. There can be multiple VLAN
IDs per IP interface; however, there cannot be two entries to the same
destination, including 0.0.0.0. On egress, this table is used to determine
whether to tag a frame that is not already marked as tagged. Egress frames
already marked as VLAN tagged (i.e. FCIP) takes precedence over entries in
this table.
NOTE: This command supports --add and --delete options only. To modify a
table entry it must first be deleted, then added with different configuration
parameters.The syntax for portcfg vlantag is as follows:
portcfg vlantag [slot/]port mode arguments
Valid modes for vlantag are:
--add ipif_addr vlan_id L2 CoS [dst_ipaddr]
Adds an entry to the VLAN tag table.
--delete ipif_addr vlan_id [dst_ipaddr]
Deletes an entry from the VLAN tag table.
Valid arguments for mode are:
ipif_add Specifies the locally defined interface address in IPv6 or IPv4 format.
vlan_id Specifies the VLAN ID used for this tag. Range is 1-4094.
L2 CoS Specifies L2 Class of Service/Priority, as defined by IEEE 802.1p. Range
is 0-7.
dst_ipaddr Optional destination IP address (IPv4 or IPv6). All packets destined for
this IP address are tagged accordingly. If a destination IP Address is not
specified, all packets not already tagged will be tagged. Default is
0.0.0.0.
