Link status command on ISE2.4

[masyamad]

Sorry for the quick question. But now I can't find ISE command to check interface link status.

For example, now eth1(gigabitEthernet 1) stays admin:up, link status:down

C:\>snmpwalk -c ro -v 2c 192.168.10.1 1.3.6.1.2.1.2.2.1.2.3
IF-MIB::ifDescr.3 = STRING: eth1
C:\>snmpwalk -c ro -v 2c 192.168.10.1 1.3.6.1.2.1.2.2.1.7.3
IF-MIB::ifAdminStatus.3 = INTEGER: up(1)
C:\>snmpwalk -c ro -v 2c 192.168.10.1 1.3.6.1.2.1.2.2.1.8.3
IF-MIB::ifOperStatus.3 = INTEGER: down(2)

In the situation, "show interface" still shows the interface is UP.

ISE/admin# show interface gigabitEthernet 1
GigabitEthernet 1
        flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.11.1  netmask 255.255.255.0  broadcast 192.168.11.255

Does anyone know good command to check the link status(ifOperStatus) on ISE?

I just walked a 2.4 node and those mibs indicate up/up for the loopback, and gigabit0 (eth0) which are the only active interfaces.

.1.3.6.1.2.1.2.2.1.2.1 = STRING: "lo"
.1.3.6.1.2.1.2.2.1.2.2 = STRING: "eth0"
.1.3.6.1.2.1.2.2.1.2.3 = STRING: "eth1"
.1.3.6.1.2.1.2.2.1.2.4 = STRING: "eth2"
.1.3.6.1.2.1.2.2.1.2.5 = STRING: "eth3"

.1.3.6.1.2.1.2.2.1.7.1 = INTEGER: 1
.1.3.6.1.2.1.2.2.1.7.2 = INTEGER: 1
.1.3.6.1.2.1.2.2.1.7.3 = INTEGER: 2
.1.3.6.1.2.1.2.2.1.7.4 = INTEGER: 2
.1.3.6.1.2.1.2.2.1.7.5 = INTEGER: 2

.1.3.6.1.2.1.2.2.1.8.1 = INTEGER: 1
.1.3.6.1.2.1.2.2.1.8.2 = INTEGER: 1
.1.3.6.1.2.1.2.2.1.8.3 = INTEGER: 2
.1.3.6.1.2.1.2.2.1.8.4 = INTEGER: 2
.1.3.6.1.2.1.2.2.1.8.5 = INTEGER: 2

Yes, SNMP query shows both admin and link status but now "show int" seems to show only admin status.

So I'd like to know if other useful way to show the link status on ISE unit (by CLI command or GUI menu)

On ISE VM, I often see the output of "show interface" not reliable. Since you are able to good results via SNMP, that would be the way to go.
