How is a converted interface numbered

Two numbering rules are available after interfaces are split: dimension numbering rule in V100R003C00 and later versions and interface sequence numbering rule in versions earlier than V100R003C00.

Numbering rules after 40GE interfaces are split:
For example, a 40GE interface is numbered 40GE x/y/n and is split into four 10GE interfaces. The 10GE interfaces are numbered using the following two rules:

1. If the dimension numbering rule is used, the 10GE interfaces are numbered 40GE x/y/n:1, 40GE x/y/n:2, 40GE x/y/n:3, and 40GE x/y/n:4.
2. If the interface sequence numbering rule is used, interfaces on different switches are numbered in the following ways (CE7800 and CE8800 series switches do not support this numbering rule.):
a. On the CE5850-48T4S2Q-HI and CE5855EI switches, a 10GE interface split from 40GE x/y/n is numbered 10GE x/y/[4n + z]. z indicates the 10GE interface location and the value of z ranges from 1 to 4.
b. On CE6800 series switches, a 10GE interface split from 40GE x/y/n is numbered 10GE x/y/[48 + 4(n - 1) + z]. z indicates the 10GE interface location and the value of z ranges from 1 to 4.
c. On CE12800 series switches, a 10GE interface split from 40GE x/y/0/n is numbered 10GE x/y/0/(4n + z). z indicates the 10GE interface location and the value of z ranges from 1 to 3.
d. A 40GE interface on a CE88-D16Q card of a CE8860EI switch can be split into two 10GE interfaces. For example, two 10GE interfaces split from 40GE 1/1/1 are numbered 40GE 1/1/1:1 and 40GE 1/1/1:2.

Numbering rules after 100GE interfaces are split:
For example, a 100GE interface is numbered 100GE x/y/0/n and is split. Take a 100GE interface on a CE-L04CF-EF card as an example. The interfaces after split are numbered using the following two rules:

1. If the dimension numbering rule is used, the 100GE interface supports the following split types:

a. If the 100GE interface is split into ten 10GE interfaces, a 10GE interface is numbered 100GE x/y/0/n:z. z indicates the 10GE interface location and the value of z ranges from 1 to 10.
b. If the 100GE interface is split into eight 10GE interfaces, a 10GE interface is numbered 100GE x/y/0/n:z. z indicates the 10GE interface location and the value of z ranges from 1 to 8.
c. If the 100GE interface is split into two 40GE interfaces, a 40GE interface is numbered 100GE x/y/0/n:z. z indicates the 40GE interface location and the value of z is 1 or 2.
d. If the 100GE interface is configured as one 40GE interface, the 40GE interface is numbered 100GE x/y/0/n:1.

2. If the interface sequence numbering rule is used, the 100GE interface supports the following split types:

a. If the 100GE interface is split into ten 10GE interfaces, a 10GE interface is numbered 10GE x/y/0/(10n + z). z indicates the 10GE interface location and the value of z ranges from 0 to 9.
b. If the 100GE interface is split into eight 10GE interfaces, a 10GE interface is numbered 10GE x/y/0/(10n + z). z indicates the 10GE interface location and the value of z ranges from 0 to 7.
c. If the 100GE interface is split into two 40GE interfaces, a 40GE interface is numbered 40GE x/y/0/(2n + z). z indicates the 40GE interface location and the value of z is 0 or 1.
d. If the 100GE interface is configured as one 40GE interface, the 40GE interface is numbered 40GE x/y/0/2n.
