Interface Nomenclature
The major difference between SFTOS and FTOS is that commands that contain a parameter in the form
slot/port in FTOS use a unit/slot/port parameter in SFTOS for both physical and logical interfaces.
For physical identifiers, the unit is the stack member number in an S-Series stack. For example, both FTOS
and SFTOS have the
show interface command, but the SFTOS equivalent of show interface
gigabitethernet 2/11
(slot 2, port 11 in FTOS) would be show interface 1/0/11, where 1/0/11
represents unit 1 in the stack, slot 0, port 11. If the port were in unit 2 of the S-Series stack, the command
would be
show interface 2/0/11.
Logical interface identifiers are automatically generated by SFTOS. They also use the unit/slot/port
convention, but system unit numbers are always 0, slot numbers are sequential, starting at 1, and the
interface numbers (in the third position) are also sequential, starting at 1 per slot.
Other CLI variations include:
•
Creating a static route: The SFTOS command ip route supports only IP addresses for setting the
next-hop router, while
ip route in the FTOS also supports physical interfaces.
•
Setting the size of the logging buffer: The FTOS command logging buffered has a parameter
that enables you to set the size of the buffer, while SFTOS does not. Both FTOS and SFTOS invoke
debug logging with the number 7 for the severity level parameter. The
SFTOS command is logging
buffered 7
.
•
Displaying the MAC address table: Both FTOS and SFTOS have the show mac-address-table
command, but the SFTOS command show mac-addr-table provides more similar results to that
FTOS command. The SFTOS syntax contains the unit/slot/port form cited above, for example,
show mac-addr-table interface 1/0/4.
• Displaying system information: The FTOS command show linecard is similar to show
version
in SFTOS, which shows basic information, including the running software version and up
time. Other similar commands in SFTOS are
show hardware and show sysinfo, and show
tech-support
provides the results of a group of those similar commands.
•
service timestamps: This FTOS command is not available in SFTOS. SFTOS sets timestamps
automatically.
•
aaa authentication: This FTOS command is available in SFTOS as authentication.
Note: Starting with SFTOS 2.5.1, the integer IDs of LAGs (port channels) and VLANs that you assign to
the interfaces when you configure them are the IDs used throughout the configuration; the system no
longer assigns a logical ID in the unit/slot/port form.
