This is
because no extended channel rear card is installed in the switch.
An S5700SI or S5700EI switch
can provide only two optical interfaces for a front card. If a 4-port front card
is installed, the switch must use an ES5D00ETPB00 extended channel rear card to
provide the other two interfaces. Without an extended channel rear card, only
two optical interfaces are displayed.
- If a 4-port GE front card (ES5D000G4S01/ES5D00G4SA01) and an ES5D00ETPC00 rear stack card (working normally) are used together in a switch, only the first and second interfaces on the front card can work normally, and the other two interfaces cannot be used.
- If a
4-port 10GE front card (ES5D000X4S01) and an
ES5D00ETPC00 rear stack card (working normally) are used together in a switch,
only the first and third interfaces on the front card can work normally, and the
other two interfaces cannot be used.
The
available interfaces on the ES5D000X4S01 front card are
displayed as XGigabitEthernet */1/1 and XGigabitEthernet */1/2 on the CLI,
corresponding to physical interfaces 1 and 3 on the front card.
* indicates
a slot ID on the switch.
