ALTER PIF Command
only for FESAs and GESAs. The value must be set by the user. There is no
default value.
MAXSESSIONS max-sessions
max-sessions specifies the maximum sessions that the adapter can handle. The
adapter pre-allocates resources to handle the sessions. The trade-off involved is
between the number of sessions and the number of transmit-and-receive buffers
for data. The range is 1 through 2000 sessions. The default is 2000.
NODEMACADDRESS { addr | DEFAULT }
addr specifies the primary MAC station address used by this node for all frames.
DEFAULT specifies that the adapter gets the MAC address from the adapter
SEEROM (the hardware MAC address). The range of values for addr is
%H400000000000 to %H7FFFFFFFFFFF.
For Token Ring, the valid non-default MAC address range is from
%H400000000000 to %H7FFFFFFFFFFF.
For Ethernet (E4SA, FESA, GESA, G4SA), the second hexadecimal digit in the
MAC address must be 2, 6, A, or E to be a valid non-default MAC address. One of
these values is needed to prevent the multicast bit from being set inadvertently.
The address is read into memory by least significant bit (instead of most significant
bit, like Token Ring); therefore, the last bit is read first, and must not be set,
because the Ethernet standard requires that the first bit be the multicast bit.
The NODEMACADDRESS is valid for all adapter types, except the MIOE and
CCSA adapters.
NOOPTION
is the dummy parameter used for PIFs on adapters other than TRSAs, E4SAs,
FESAs, GESAs, G4SAs, and ATM3SAs. NOOPTION provides the INFO PIF,
OBEYFORM command output for all other adapters. The NOOPTION parameter
causes the SLSA subsystem to ignore the ALTER PIF command. The NOOPTION
parameter cannot be used with any other parameter.
RINGSPEED { 4 | 16 }
specifies the speed of the token-ring. The speed is either 4 or 16 mbps. The
default is 16. RINGSPEED is supported for TRSAs only.
Considerations

The PIF object must be in the STOPPED state before you can alter it.

You must specify at least one attribute.

The ALTER PIF command supports the ATM3SA, TRSA, E4SA, FESA, GESA, and
G4SA PIFs. The ALTER PIF command does not apply to a CCSA since a CCSA
does not have any alterable PIF attributes.
