i need to use the port id of port in 7750 for snmp request .
SNMPv2-SMI::enterprises.6527.3.1.2.4.3.6.1.1.X.Y.Z
where x = service id
y = port id
z= vlan
can some one tell me how can i calculate the y ( port id ) base on 7750 ?

You could poll ifName. (1.3.6.1.2.1.31.1.1.1.1)
Code: Select all
iso.3.6.1.2.1.31.1.1.1.1.37912576 = STRING: "1/2/5"

the user manual says thats is in binary.

Also, the definition of TmnxPortID in the MIBs explains how you can calculate it:
Code: Select all
TmnxPortID ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A portid is an unique 32 bit number encoded as shown below.
32 30 | 29 26 | 25 22 | 21 16 | 15 1 |
+-----+-------+-------+-------+-------+
|000 | slot | mda | port | zero | Physical Port
+-----+-------+-------+-------+-------+
So port 1/2/5 i.e. slot 1, mda 2, port 5 would be in binary (adding whitespace for readability):
000 0001 0010 000101 000000000000000 which is 37912576 in decimal
