Command Modes
config-applet
Command History
|
|
5.2(1) |
This command was introduced. |
Usage Guidelines
This command does not require a license.
Tag names have scope only within the policy they are defined in. Tag names must be already configured in event commands before they can be used in a tag command.The evaluation of tag logic operators is from left to right since all operators are of equal precedence, that is:
((tagA operation1 tagB) operation2 tagC) operation3 tagD |
When a cli match event is tagged, the behavior changes compared to untagged cli match events. Commands matching a tagged cli match event are executed immediately. If this were not the case, there may be a delay while waiting for other tagged events to match before an event-default command in the applet action block is executed.
Examples
The following example shows how to use the tag command. The goal in this example is to save the latest core dump to bootflash (it could also be sent to an SFTP server etc). The first policy is triggered when a process crash is about to generate a core file. It sleeps for 60 seconds while the core file is generated and then increments a counter. The second policy monitors the counter as well as system switchover events. If the counter is greater than 0 and no switchovers have occurred in the last 60 seconds then the latest core file is copied to bootflash and the counter reset to 0. No exit-op is specified for the counter so that the second policy can be triggered multiple times at once.
switch# configure terminal
switch(config)# event manager applet coreDump
switch(config-applet)# event syslog pattern "SERVICE_CRASHED.*core will be saved"
switch(config-applet)# action 10 cli local sleep 60
switch(config-applet)# action 20 counter name cores value 1 op inc
switch(config-applet)# event manager applet saveCore
switch(config-applet)# exit
switch(config)# event manager applet saveCore
switch(config-applet)# event counter tag coreDumped name cores entry-val 0 entry-op gt
switch(config-applet)# event syslog tag swDone pattern "SWITCHOVER_OVER"
switch(config-applet)# tag coreDumped andnot swDone happens 1 in 60
switch(config-applet)# action 10 cli local sh core | last 1 | sed 's/ \+/ /g' | sed 's_\([0-9]\+\) \([0-9]\+\).* \([0-9]\+\).*_copy core://\1/\3/\2 bootflash:_' | vsh
switch(config-applet)# action 20 counter name cores value 0 op set
switch(config-applet)# exit

Usage Guidelines
You can configure an iSLB initiator target using the device alias or the pWWN. You have the option of specifying one or more of the following optional parameters:
- Secondary pWWN
- Secondary device alias
- LUN mapping
- IQN
- VSAN identifier
Note The VSAN identifier is optional if the target is online. If the target is not online, the VSAN identifier is required.
If you configure an IQN for an initiator target, then that name is used to identify the initiator target. Otherwise, a unique IQN is generated for the initiator target.
Examples
The following example configures an iSLB initiator using an IP address and then enters iSLB initiator configuration submode:
switch(config)# islb initiator ip-address 209.165.200.226
The following example grants iSLB initiator access to the target using a pWWN with auto zoning enabled (default):
switch (config-islb-init)# target pwwn 26:00:01:02:03:04:05:06
The following example grants iSLB initiator access to the target using a pWWN with auto zoning disabled:
switch (config-islb-init)# target pwwn 26:00:01:02:03:04:05:06 no-zone
The following example grants iSLB initiator access to the target using a device alias and optional LUN mapping:

Command History
|
|
1.1(1) |
This command was introduced. |
6.2(5) |
The IPStorage support was increased to 10G on the Cisco MDS 9250i Multiservice Fabric Switch. |
6.2(13) |
The maximum bandwidth of iSCSI was increased to 10G. |
Usage Guidelines
The maximum-bandwidth option and the round-trip-time option together determine the window size. The maximum-bandwidth option limits only the IPStorage traffic and not the FCIP traffic or the iSCSI traffic.
The minimum-available-bandwidth option and the round-trip-time option together determine the threshold below which TCP aggressively increases its size. After it reaches the threshold the software uses standard TCP rules to reach the maximum available bandwidth.
When configuring tcp bandwidth using the tcp maximum-bandwidth-kbps and tcp minimum-bandwidth-kbps commands, the value should not exceed the maximum speed of the physical IPStorage port.
The maximum and minimum tcp bandwidth of all the FCIP and iSCSI interfaces that are using a specific Gigabit Ethernet or IPStorage port should not exceed the maximum speed of the physical IPStorage port.
For optimal performance the minimum-bandwidth-kbps should be 80%-90% of the maximum-bandwidth-kbps.
Examples
The following example configures a FCIP profile:
switch# configure terminal
switch(config)# fcip profile 5
The following example configures the maximum available bandwidth at 900 Kbps, the minimum slow start threshold as 300 Kbps, and the round trip time as 10 milliseconds:
switch(config-profile)# tcp max-bandwidth-kbps 900 min-available-bandwidth-kbps 300 round-trip-time-ms 10
The following example reverts to the factory defaults:
switch(config-profile)# no tcp max-bandwidth-kbps 900 min-available-bandwidth-kbps 300 round-trip-time-ms 10
The following example configures the maximum available bandwidth at 2000 Kbps, the minimum slow start threshold as 2000 Kbps, and the round trip time as 200 microseconds:
switch(config-profile)# tcp max-bandwidth-kbps 2000 min-available-bandwidth-kbps 2000 round-trip-time-us 200
The following example configures an iSCSI profile:
switch# configure terminal
switch(config)# interface iscsi 1/1-2
The following example configures the maximum available bandwidth at 9000000 Kbps, the minimum slow start threshold as 8000000 Kbps, and the round trip time as 20 milliseconds:
switch(config-if)# tcp max-bandwidth-kbps 9000000 min-available-bandwidth-kbps 8000000 round-trip-time-ms 20
The following example reverts to the factory defaults:
switch(config-if)# no tcp max-bandwidth-kbps 10000000 min-available-bandwidth-kbps 8000000 round-trip-time-ms 20
The following example configures the maximum available bandwidth at 5000000 Kbps, the minimum slow start threshold as 4000000 Kbps, and the round trip time as 200 microseconds:

trunk protocol enable
To configure the trunking protocol, use the trunk protocol enable command in configuration mode. To disable this feature, use the no form of the command.
trunk protocol enable
no trunk protocol enable
Note Trunk protocol is enabled by default from Cisco MDS NX-OS Release 6.2(7) and later.
Syntax Description

Command History
|
|
1.0(2) |
This command was introduced. |
6.2(7) |
This command was deprecated. |
Usage Guidelines
If the trunking protocol is disabled on a switch, no port on that switch can apply new trunk configurations. Existing trunk configurations are not affected—the TE port continues to function in trunking mode, but only supports traffic in VSANs that it negotiated previously (when the trunking protocol was enabled). Also, other switches that are directly connected to this switch are similarly affected on the connected interfaces. In some cases, you may need to merge traffic from different port VSANs across a non-trunking ISL. If so, you need to disable the trunking protocol.
Examples
The following example shows how to disable the trunk protocol feature:
switch(config)# no trunk protocol enable
The following example shows how to enable the trunk protocol feature:
switch(config)# trunk protocol enable
