LACP for MPLS packets

Hello.

We are using Dell Force10 switch as a transit switch with LACP port channel.
When traffic is going across port channel - traffic is going only in one interface.

What type of hash algorithm we need to set?
Is this config will solve our ptoblem?

kiev_gdr50_dell(conf)#hash-algorithm ?
ecmp Options for ECMP hashing
lag Options for Lag hashing
seed Hash Algorithm seed for ECMP, LAG
kiev_gdr50_dell(conf)#hash-algorithm lag ?
crc16 CRC16_BISYNC - 16 bit CRC16-bisync polynomial
crc16cc CRC16_CCITT - 16 bit CRC16 using CRC16-CCITT polynomial
crc32LSB CRC32_LOWER - LSB 16 bits of computed CRC32(default)
crc32MSB CRC32_UPPER - MSB 16 bits of computed CRC32
xor1 CRC16_BISYNC_AND_XOR1 - Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor1
xor2 CRC16_BISYNC_AND_XOR2 - Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor2
xor4 CRC16_BISYNC_AND_XOR4 - Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor4
xor8 CRC16_BISYNC_AND_XOR8 - Upper 8 bits of CRC16-BISYNC and lower 8 bits of xor8
xor16 CR16 - 16 bit XOR
