ALTER MON Command for TCP6MAN
The supported incoming ICMP packets (type, bit, hex value) are currently
supported:
The default value is %H00000000.
Examples

To alter the DELAYACKS and DELAYACKSTIME attributes on all configured
TCP6MONs:
-> ALTER MON $ZZTCP.*, DELAYACKS ON, DELAYACKSTIME 20

To alter the TCPSENDSPACE to 4096 on all configured TCP6MONs:
-> ALTER MON $ZZTCP.*, TCPSENDSPACE 4096

To change the TCP and UDP port range to 32768 to 65535:
-> ALTER MON $ZZTCP.*, MIN-EPHEMERAL-PORT 32768

To alter the NonStop TCP/IPv6 subsystem TCP-MAX-REXMIT-COUNT attribute on
all configured monitors:
-> ALTER MON $ZZTCP.*, TCP-MAX-REXMIT-COUNT 10

To filter the ICMP_ECHO packet:
-> alter MON *, ICMP-FILTER-PKTS %h00000100

To filter the ICMP_ECHO, ICMP_TSTAMP and ICMP_MASKREQ packets:
-> alter MON *, ICMP-FILTER-PKTS %h00022100

To filter all the supported ICMP packets (ICMP_ECHO, ICMP_TSTAMP,
ICMP_IREQ, ICMP_MASKREQ and ICMP_REDIRECT):
-> alter MON *, ICMP-FILTER-PKTS %h0002a120
Considerations
The MIN-EPHEMERAL-PORT and MAX-EPHEMERAL-PORT attributes have been
added to allow you to modify the ephemeral port-range used by the TCP6MONs to be
more usable in your environment. The ephemeral port range is between 1024 and
65024. Each processor is allocated one sixteenth of this range.
Prior to the G06.24 RVU, if two applications in the same processor bound to a local
port and specified different addresses, the bind would fail. However, if the applications
