Change Port Name SNMP String

[Rodrigo_Barbier]

Hello, I need to change the name of the port SNMP String.

With the command "configure ports 1:3 display-string tester" a string of port really changed, but when I look at the values ​​SNMPWalk return:

IF-MIB :: ifDescr.1003 = STRING: Stack Port 1: 3

What is the command to change this string for example "Stack Port 1: 1" to "tester"

Daniel,
checking the Mib really exists ifAlias.

I used the ifAlias in Zabbix graphs and showed the name I needed.

Thanks to all

Can you please tell me how do you change use ifAlias . Currently i am also trying to see Port Description in SNMP sever side. When port up down happen snmp traps send to the server then send to Administrator for alert messages via email. Currently can only see .1013 mean 10 switch 1 port number 13 up down etc. can't see the port description. Appreciate your help! Thanks.

I forgot to mention that ifDescr is READ ONLY. That's why you couldn't change it...

Use ifAlias instead.

Rodrigo,

Since v15.3 we have both Display-String and Description-String:

• Display-string has a maximum length of 20 characters and does nos accept spaces.
• Description-string has a maximum length of 255 characters and accepts spaces.

Show port info will display the display-string.

Port Flags Link ELSM Link Num Num Num Jumbo QOS Load
State /OAM UPS STP VLAN Proto Size profile Master

PortDisp> Em------e--fMB----- active - / - 5 0 2 0 9216 none

Show port info detail will display both the display-string and the description-string

Port: 1(PortDisplayString😞
Description String: "This Is The Port Description String"

Whatever you write in the MIB variable ifAlias (1.3.6.1.2.1.31.1.1.1.18) will show both in Description String and in Display String (truncated to 20 chars).

If you only set Display-String, it will appear in ifAlias. But if you set Description-String, it will replace the Display-String value in ifAlias. If you then change Display-String, ifAlias won't change, unless you unconfigure Display-String...

Confusing, I know...

I've been playing with NetSight MIB Tool and EXOS v15.6.1.4
