46-4 ip mtu
This command is used to set the Maximum Transmission Unit (MTU) size of IP packets sent on an interface. Use the
no form of this command to restore to the default setting.

46-5 ip ecmp load-balance
This command is used to set the load-balancing algorithm for ECMP/WCMP route. Use no form of this command to
remove the configuration set before.
ip ecmp load-balance [{sip | crc32_lower | crc32_upper} | dip | port](1)
no ip ecmp load-balance [{sip | crc32_lower | crc32_upper} | dip | port]
Parameters
sip
crc32_lower
crc32_upper
dip
port
DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
Specifies the Maximum Transmission Unit of an IP packet. The value range is 512-
1712.
The default value of IP MTU is 1500
Interface Configuration Mode.
Level: 8
If an outgoing IP packet from CPU interface exceeds the MTU set for the interface,
software will fragment it before sending out.
Note: Changing the MTU value (with the jumbo frame command) won't affect the IP
MTU value, vice verse is same. Therefore you should care both MTU and IP MTU
sizes to make the system working correctly. For example, if IP MTU is larger than
MTU at the egress port, the packet larger than MTU but less than IP MTU may be
dropped by the egress port.
Use show ip interface to see the current setting of IP MTU
This example shows how to set the IP MTU of interface 'vlan1' to 800 bytes.
(Optional) Specifies that the load-balancing algorithm will include the lower 5 bits of
the source IP address. This attribution is mutually exclusive with crc32_lower and
crc32_upper. If it is set, crc32_lower and crc32_upper will be excluded.
(Optional) Specifies that the load-balancing algorithm will include the lower 5 bits of
the CRC. This attribution is mutually exclusive with crc32_upper and sip. If it is set,
crc32_upper and sip will be excluded.
(Optional) Specifies that the load-balancing algorithm will include the upper 5 bits of
the CRC. This attribution is mutually exclusive with crc32_lower and sip. If it is set,
crc32_lower and sip will be excluded.
(Optional) Specifies that the load-balancing algorithm will include the destination IP
address.
(Optional) Specifies that the load-balancing algorithm will include the TCP or UDP
port.
